The apartment is in a good location. The metro station and several sights are close by. There are a couple of restaurants downstairs, so you can hear street noises, but the windows are properly insulated and if they are closed, then you barely hear any noises. The nights are quiet, at least in the fall. So you get a good night's sleep.
The apartment is quite spacious. There is everything you need for everyday life. The kitchen is well equipped and you can prepare even finer dishes.
In the beginning there were problems with the internet. It was really slow. Finally, the technician installed an optical cable in the apartment. After that everything was great. During one month stay I had only one problem (the internet one) and I didn't feel I was left alone with my problem, because the host was actively looking for solutions. That shows something.
