This is a hotel experience, rather than staying in someone's private apartment. The hotel is very modern, in a restored old building, and has everything you would expect in a mid range tourist hotel. The tea & coffee facilities in the room could be I improved with milk supplied, and normal coffee, we only had decaffienated left on our 3 day stay. The room and other areas in the hotel are very clean, the bed was very comfortable, and our room (not facing the street) was very quiet. There's a lift, and the rooms are air conditioned.
As a hotel, there's reception that operates 24 hours, and we found all the staff very friendly and helpful, with tips for sightseeing and getting around. Nikita, who we met on Sunday, was outstanding and gave us the BEST tip for somewhere to go on a hot day, that wasn't full of other tourists. You'll have to ask Nikita for this tip, it's a gem, so we don't want the rest of the world to hear about it.
Prague at night is not always safe, and this hotel is not close to all the tourist attractions, so it's a good idea to get your head around the metro and tram systems. A ticket will get you onto both modes of transport, and the metro and tram are both within 500 metres of the hotel.
