The Czech Inn hostel was the BEST imaginable option for my first time in Prague. I will absolutely be staying at the Czech Inn for my next visit to Prague. The on-premises bar was not open every night, but when it was open, I had a great time meeting fellow friendly travelers and it was lovely meeting friends in the lobby and café as well. It was a quiet, comfortable, and safe accommodation and I couldn't recommend it enough. I booked a single room though, just so you know! I did not have the dorm bed experience but lots of the friends I made did and had a good experience as well.
