My boyfriend and I were warmly welcomed by Maria's friend, Emilio, who provided helpful information on the city and apartment (even though it was past midnight).
The apartment is just as on the pictures, really clean, convenient, overall really nice. Though it's on the ground floor, you can't really see outside and it's a bit dark (I'm guessing it's cool during summer).
There is everything you need in the apartment.

The bad side is that there was some construction going on in the alley of the apartment. The workers were making a hole in the pavement litterally under the window which was obviously extremely noisy. On Friday and Monday, we were woken up at 8 am by drills and chainsaws and it was impossible to sleep :(

The location is great (close to all attractions). The neighborood looks calm and feels safe.
