We, 6 women, stayed here for my 40th birthday and it was a perfect space for us.
The flat is on the 4th floor and there is a lift so there are not accessibility issues. There is plenty of space, although I could imagine it could get crowded if 10+ people were all staying there. It is located 10 minutes walk away from the Sagrada Familia (which is a must see btw – book in advance!). It is a short walk to the metro, but we found it easy to get taxis everywhere and they are very good value!
The apartment has a lovely roof terrace and great for chilling out after a day’s meandering through the streets.
A great space for spending time in Barcelona!
