We stayed in a twin room with private ensuite and it exceeded our expectations by leaps and bounds. Because it was February we only had to pay 22 Euros each, such a bargain considering we paid the same price for a closet-sized private room with bunkbeds in Strandhill the night before.

After reading mainly positive reviews online, we felt that Sleepzone would be a safe choice, but were still not sure exactly what to expect. What we got was a very convenient location, a good-sized immaculate private room with our own shower/toilet and a sky light, very friendly and helpful desk service, and a great night in a wonderful town. Because it was Sunday night, we were able to park for free in the parking lot about a block away. We bought a ticket from the machine to cover us for the next day and it cost next to nothing.

And if you're looking for affordable dinners, try Finnegans Traditional Irish Restaurant on Market Street. It wasn't listed on the sheet/map from Sleepzone but it was great. Only 9.95 euros for a huge and fabulous sheperd's pie with all the trimmings. And the pizza at the King's Head pub looked great and it was around 10 euros. Be sure to check out the Quays pub too, fabulous place.

Having stayed in Sleepzone many times a couple of years ago, I was looking forward to my stay again. On arrival, after checking in and leaving a ten euro security deposit, we were told that we were staying in a house across the street from sleepzone. The house was nice and clean and so was the room but the beds were absolutely terrible. They squeked so much that the two of us were awake half the night. As others have said the streetnoise is terrible too. You can hear everyone walking past. The fuse thing is also very annoying,especially as you are sharing a house with people, asking them to stop boiling the kettle so you can have a shower is a bit inconvinient. We decided to end our two night stay and only stay for the one night as we were just a bit unhappy.
Pros
Clean
The staff are very friendly and helpful
Good security as long as you were in the main building
Free internet access
Breakfast-although we werent there in time
The €3.50 car park down the road

Cons
I would have felt a bit worried had it been two girls staying in the house. There is no security at the house that we were staying so you dont know who you're staying with and unlike the main building you werent able to run down to the security guard
The beds are so noisy that you cannot get a good sleep
The street noise
Not being told about the security deposit until arrival
€10 deposit per towel is also a bit steep

We have always stayed in private rooms and they were always in the main building before and were a bit more comfortable so Im not sure why they changed it

The hostel was very clean and very central which was good. However, there were lots of 'hidden' extras. We were a group of 5 and it wasn't until we booked in that we were told we had to pay a deposit for each key, a deposit for the towels (which I suppose isn't that unusal for a hostel) and a security deposit per person.

All this is fine in theory, however we were not told this when booking rather when we were checking in. Also we were told that the security deposit (25 Euro per person) would only be taken as a pre-auth off the card and 'cancelled' after 48 hours. This was not the case - it was taken off the card and then put back after we checked out, causing us to loose £5 in the transaction.

The staff were friendly - didn't make it in time for the free breakfast.

We had a pleasant stay here in a twin bed room. The non-shared rooms are separate from the main hostel building, across the street in cute little renovated townhouses. Since the renovation is very recent, the full shared kitchen (there's one in each townhome) and property are nearly new and pleasantly modern. The room was spacious and sunny and the beds comfy with their own comforters/sheets/pillows included. The showers were kind of strange (very noisy from some electric generator that heats the water and you're warned not to use them when the kitchen downstairs is in use because a fuse might blow) although clean and convenient. Just remember it's a hostel so you have to bring all toiletries and towels (although you can get towels/hairdryer if you leave a huge deposit at the front desk). There's a barebones continental breakfast also available in the main building.

The location is very convenient, on a seemingly quiet street just off the main downtown area and right near a major shopping center with Marks and Spencer supermarket and more, so getting food for the kitchen is a breeze. Remember the whole town is really tiny, safe and walkable, so don't listen to the reviews that make it sound like it's far out of the way. Unfortunately the street doesn't stay quiet late at night as young drunken revelers return from the bars. If you can request an off street room you should; unforunately I never got a good night's sleep in Galway from all the partying students in the street. Also the rooms are thin in the house itself, and the loud showers, and the impossible to open main door lock (which you'd hear people struggling with at all hours) added to noise levels.

Overall great for the money, clean and modern, but try to get an off street room if you want an actual "sleepzone."
