Thanks for the accommodation, Choco! It was very clean and the price was reasonable. It's about 15-20minutes from center by car but there is also a metro station 3 minutes by a walk. The street is a little bit shady for first sight at the evening but we didn't experience anything bad. Also very good breakfast fast-food right next to the apartment. For the price, it's a very good choice!
PS - well working WIFI in appartment
