We only stayed here for three nights but it gave us just what we needed - a comfortable space to stay in a great location to explore the Old Town. The check-in process was fine - there was some advance forms to fill in and extra city tax to pay to but we expected it and didn’t mind, it’s important for managing tourism sustainably in Barcelona. The office for signing in and collecting the key on arrival is just two minutes’ walk away from the apartment, and the staff were really friendly and helpful.
A couple of small things to note: the shower temperature was a bit tricky to control, and we couldn’t get the TV to work - but these things didn’t affect us very much as we were only there for a couple of days and were mainly out in the city anyway. Also, it’s up several flights of stairs with no lift.
