First, this location is ideal being centrally located between La Rambla and major sights like Sagrada Familia. Lots of great restaurants and bars all within 20 minutes walk.
We had a group of five and this apartment was a perfect size for our group. When we hung out there we did not feel cramped. The high ceilings help the place seem large. The balcony is as also a great addition.
The hosts were attentive to our needs and the place exceeded our expectations.
