4 of us recently stayed as a suprise for Sister-in-laws 40th birthday. The hotel sits right by the river (hence the name, but you do visit hotels who's name has nothing to do with its situation!!) and is a 10 - 15 min walk along the river to the heart of the city. The staff are 'serious looking', not grumpy as others have said, but very helpful and incredibily well presented (they could teach English hotel staff a thing or two!)
We had 2 'mini suites' which where beautiful, clean and modern with fantasic bathrooms, not massive but very well kitted out.

My only word of warning was breakfast which cost £18 each! The lady who served us was brilliant/ bonkers (should have her own TV show)

Like it says,more of the same! Stayed 4 nights over new year 2006/7. Excellent clean hotel, superb staff, and great location, a few minutes' walk from Mala Strana, and close to tram and metro stops. I would recommend wholeheartedly.
Breakfast is a bit expensive, but the lady who runs it will ensure that you get your money's worth! Not a huge wardrobe either, but this is very much a minor point.
Five stars.

I'm a Prague regular, I've travelled to Prague on various budgets and stayed at various hotels. I was thorougly impressed. I ended up in Prague for New Year 2006/2007 alone and I was happy I made the decision to stay here. The welcome from the staff was impressive, I was instantly seated in the bar and handed a welcome drink whilst I completed my registration (although I was 2 hours earlier than official check in). The helpful reception team handed me maps and advice of where to shop and where to go, this of course was not necessary for me but would be very handy to a first timer.

As I entered my room I noticed a little cellophane package which was some biscuits, with a hand written personally addressed note welcoming me to the hotel. The room was immaculate, and view of the river and dancing building spectular both by day and night. I was also impressed by the turn down service at night, its a little thing but a very nice touch. Also available in the rooms umberella, slippers, bathrobes, hair dryer, corkscrew, as the minibar contains proper half bottles of wine. The only little comment mainly for the British is that the room doesn't have tea/coffee making facilities (this isn't an issue for me but the British can be particular over this!!).

As a guest over New Year I wasn't really expecting anything any different, although the day before New Years eve all the guests were invited into the bar for an early drink to welcome the New Year in with sparkling wine, and a chat with the manager. This I thought was a really nice touch. Also breakfast on New Years day was extended.

The bar does have character and as a solo traveller I found chatting to the staff a great help, it is expensive compared to the rest of Prague but its a 4/5 star hotel so what would you expect? Also their complimentary laptop use and inernet access was welcomed.

Check out was effortless, leaving my luggage for the day was fine, and the taxi the reception staff ordered me was 10 minutes early, and well within the price I asked to expect to pay.

Would I stay here again? without hesitation.
Would I recommend? Definately and I will.

I would recommend staying at the riverside. It is a very comfortable hotel with large rooms (i was in junior suite), a 20 minutes walk far from the messy center, wonderful bathrooms and a good level service. In general good and warm atmosphere.
Both welcoming staff, housekeeping and room service people are really kind and smiling.
Breakfast is a little too expensive but you can have coffee and something to eat in your room at reasonable prices.
The hotel location is ideal for those who don't want to be sorrounded by thousands of noisy tourists and who don't mind walking or taking tram or bus (the most punctual and timely I have ever seen anywhere in the world).
