We had such a nice stay at Oscar's place. This penthouse is amazing. It has a small terrace where we enjoyed our evenings with a glass of wine. The view is amazing. It overlooks a beautiful part of the city with small backyards and gardens. Also everything you need is nearby: Groceries, restaurants, metro and so on. Park Guell. We can recommend staying here.
Only thing which was a bit tricky: Parking. It says street parking, but there are just parking spaces for residents in the area.
