We had a great stay at Isidre‘s apartment! The apartment is very well located as there can be reached an underground station within a few minutes of walk. The line which goes there has a stop on each important attraction.
Also to mention that the check in was very well organized. Isidre showed us the whole apartment and also gave us a brief instruction on the must-see attractions of Barcelona.
We were a group of 4 people who stayed for 5 nights at the apartment. Each of us had enough space and and the size and the equipment of the flat is absolutely perfect for a city trip.
