The apartment is spacious and beautiful.
Beds are good. One of both rooms is nicely dark at night, the other room is a bit less dark. Traffic is super busy, even at night. So when you're sensitive to noise, bring your earplugs.
Good location: about 10 to 15 min walk from the metro station (from which you can directly go to the airport), and about the same distance to go to the "real" city centre. There are a few cosy and small restaurants in the very close neighborhood.
What we exceptionally liked: we once forgot the key inside the apartment, so we locked ourselves out... Within 15 minutes the problem was solved and someone came to the apartment to let us in! :-)
What we didn't like so much
* It's impossible to get fresh air in the sleeping rooms: when you open the windows, you don't reach the "outer space" with fresh air, but some kind of internal air system (making other smells, like cigarettes, enter the room)
* not even salt, pepper or oil available in the kitchen
