This space was perfect for our stay in Barcelona. We loved having two separate rooms (traveling with my 22-year old niece and my 80-year old mother).
The location was excellent, and we were never lost because we only had to look for the Sagrada Familia and the apartment was so close. It was also on a side street, which meant it was more peaceful.
We didn't use public transportation but it would have been easy to catch just a few minutes away.
The hosts were extremely helpful and responsive. They booked a nail appointment for us and ordered us a taxi for our departure. They also provided personalized recommendations for restaurants. Any time I texted them, they answered right away.
If you come to Barcelona, I would recommend this space. We loved it.
