Exellent location, you can even walk everywhere and view is to river, in mornings I looked amazing sunrises. Tram is easy, use map by location finding rutes.
Upstairs is very hard bed, I got lots of pain could not sleep there. Travelled with my child so we needed two beds. There is washing machine so we washed also towels, I missed more towels cause staying 5 nights. Pillows are very big if yo have not used to such.
Wifi was broken, in first day we told about it with several messages and in evening someone came and brought another wifi for us, that was great. Host offers sleepingmasks and earplugs.
Near is Billa and Albert supermarkets buy food. We live in Finland and brought our own coffee, here we drink very different coffee than in Prague.
Contacting to host was easy and fast. It says in add avainboksi=keybox, but its not, you have to get keys from their office in Revolucni street.
