Nadia has a beautiful apartment. It's quite spacious, with one master bedroom and two sleeping couches (one in another room and one in the living room). The apartment is in a very nice neighbourhood, we felt very safe their, even in the late evening.
If you like to walk, than the city center with his tourist attractions is walkable, or if you don't like walking, then take the subway (not far from the apartment).
Although we didn't got to see Nadia, the check-in/check-out went smooth.
Just one small note; their is a parking space in the building. But if the guest spaces are full, you have to park in the streets. So your'e not always sure if there is a parking space in the building.
We had a wonderful time and I would stay here again!
