The apartment is exactly as in the pictures in a great area within walking distance from the main train station and plenty of tram/underground stops. The area is nice, a lot of great bars and restaurants (check out Chana and Rocky Pompadour - so good).
Vinc' was nice, his guides were helpful. He was also super easy o get in touch with before we checked in, giving tips on how to get to the apartment and things. He was a lot quieter once we were actually staying in the apartment. But check in and check out times were extreme flexible and Vinc' let us keep our cases in the flat until we needed to leave for our flight. We'd definitely recommend it.
