All in all, we had a good experience in Mercedes's place. The apartment is exactly as it looks on the photos. It's bright, modern and it has everything that you need. The terrace is pretty cool, too bad we the weather didn't allow us to spend more time on it.
Apartment is located 5 minutes to metro, which is good.
Mercedes was fast responsive and also saved us when we arrived at midnight, and "call to open the doors" system didn't work.
The floor wasn't really the cleanest, which wouldnt bother us, if we weren't traveling with a baby...
