We had a nice stay in Barcelona and the Airbnb offered everything we wanted and needed in terms of the amenities.
The location is great, very close to different public transport options but also within walking distance of several sights.
We only had a slight problem when arriving because the main door wouldn't open with the app but we believe that will be fixed soon. Instead, we were welcomed by the host's kind mother so everything was ok in the end.
The host was also very responsive and thourough in his instructions.
