The apartment was a perfect size for our group of 3. The flat is very quiet and yet really well located for exploring the city. Close to several Metro stations and of course the Sagrada Familia. We ended up exploring most of the city on foot, however, due to the very central location.
Leyla was very communicative both before and during the stay. It is worth communicating your check-in time in advance as this is an in person check-in and there was a late fee for checking in at night that we weren't aware of until the day before our arrival.
