Albert's apartment was a wonderful stay for us while in Barcelona, he was very accommodating with the timing of our arrival and departures, and made sure we felt at home while also providing any help we asked for. The apartment itself is located beautifully, within 2 blocks of the nearest metro station, and there are many locations to visit around there like Sagrada Familia and Hospital de Sant Pau.
One thing we wished a little better for was some more privacy - they had to come in and fix a faulty balcony door while we were in the apartment, instead of asking if there was a better time to return in our absence. The shower itself did not drain very well, something that could be fixed up very quickly but also laid a slight inconvenience on our trip.
Overall, the apartment itself slept wonderfully and had a great location, and it definitely helped make our trip more memorable.
