We (3 women) stayed for a week in this lovely apartment. The location is great, we could reach everything by simply walking but the tramstation ist right in front of the door if you would prefer to use that. Because of that it gets loud in the night, it didn't really bother me but my friends had some problems falling asleep, so if you have a problem sleeping when it's loud then you might need to look for another location.
Our host was always fast to reply if we had any questions our only problem was the fact that he didn't really supply us with toilet paper. There was one half used roll of toilet paper in the bathroom and nothing else. After we asked him he told us that we won't be supplied with more and have to get our own. This was quite frustrating since we were 3 women staying for a WHOLE week and not even giving us a whole roll was really rude.
Aside from that we enjoyed our stay in Prague.
