I have been more than several times in Prague, and this neighborhood is one of the best you can get. You can rest from the tourist crowd but you also have local shops, beautiful caffès, restaurants and everything else what you need. Just explore the neighborhood.
Public transport is few steps away where it can take you to city centre in 15 minutes.
Apartment is spacious and comfortable. We had some difficulties with the bed but Sona arranged it all. She is a very proactive host.
I recommend this apartment for your stay in beautiful Prague.
