Four days with wife and a 15 yo daughter.
Best position to visit Barcelona, in the heart of Barrio Gotico and very close to the Ramblas (but extremely quiet).
Old building in bad shape, especially the stairway, but: don't fix at your first impression, in a few minutes you will appreciate it as well, feeling to be part of old Barcelona.
The apartment was very big and clean, well equipped and looked as the photos on airbnb. Just be careful to the second room, you need to pass through it to go to the kitchen; not a problem if you have children, some more in case of group of friends.
Everything worked perfectly during checkin and out.
We'll be back for sure chez Matthieu and Adriana.
