Good points - the staff were friendly and welcoming, and lobby and room in which we stay had recently been refurbished and were spotlessly clean.
Bad points - the beds were very uncomfy, the purple hotel name on the outside of the hotel shone through the top of the bedroom curtains to create a purple glow in the room. This along with a green safety light in the room (I can only assume it was there for reasons of safety) and light shining in under the bedroom door meant that when the lights were turned off, you could still see everything! I ended up sleeping with a pillow over my head to block out the light and the snoring from next door. Not great. We ended up putting a towel over the top of the curtains and a t-shirt over the green light, which helped a bit. The bath was sloping and very dangerous to step into to shower. The breakfast was chaos - the staff were very friendly when I managed to attract their attention but there were no glasses left, we weren't asked if we wanted a hot breakfast etc... We had to pay for parking, which seemed odd. When we checked out we weren't asked how our stay was.
All in all I would not go back. I think the rooms, whilst they have been refurbed and do look good, haven't been carefully thought through as beneath the clean surface, there are sleepless nights awaiting you at the Croham!! We booked the room in a rush and stupidly didn't check trip advisor beforehand!
