If you're looking for a quite and private apartment, but within reach of metro and a lot of tram lines, this is a really good choice.
I enjoyed reaching all the interesting places in Prague either by foot or by public transportation.
The nearby commercial center with cafés, restaurants and a huge shopping mall is also a welcome addition.
The apartment is located in a quite residential street, very good equipped (kitchen, bath) with lots of details I rarely found in other locations. Also the place was carefully cleaned. I felt really "at home".
Huyen is a very friendly and helpful guy. I really enjoyed staying at his apartment.
