I would recommend this BB for people who are on a budget and/or if you are staying longer than 3 days in Prague because it is not that close to the city center. The metro station is close, but the tram is about 20-minute walk and the walk back is all uphill. The owner suggested a shortcut, however, it was all stairs so it was not a very good alternative.
If you are on a budget and can't stay in downtown I would suggest finding a place that is closer to public transportation, particularly the tram because otherwise you will waste a lot of time back and forth. The room was very big and the breakfast was good as well. I gave 4 stars for service because the guy was late picking us up from the airport, after missing our connecting flight to Prague (our flight from US to Europe was 5 hours late) and having slept only 3 hours the night before, it would had been very nice not to wait to be picked up from the airport. I think next time we will pay a little extra and stay in downtown.
Traveling Tip: To save money on transportation, particularly to the airport use Uber, it is half the price of taxis. We used it several times and the service was very good, we never had a problem. We also used it in Zagreb and Dubrovnik.
