We lived in the apartment for 3.5 months. The apartment was really nice and spacious. It had everything we needed (dishes, cooking utensils, clean towels and sheets).
The neighbourhood was peaceful and safe. There are also beautiful outdoor areas right around the house where you can admire the view of Barcelona city and the sunset. The transport connections were very good: Placa Catalunya is easily accessible either by bus in front of the house or by metro in 20-30minutes. It was also not a long walk to the grocery store.
Xenia was friendly and helpful if we needed help with anything and she speaks good English. We would definitely recommend Xenia's apartment!
