Me and my two friends stayed for one week at Andrea's appartment and we loved it! It is spacious (the two-bed-room is small but still ok), well equipped (kitchen equipment, dish washer, washing machine), clean and air conditioned (if needed). The balcony is small but still really nice to have.
The location of the appartment is really good: close to Plaza de Catalunya (where aerobus and many other public transport is located) and around the corner of Arc de Triomf (metro). Walking distance to many sights and nice quarters (Barric Gotic, L'Eixample...) and - a bit longer - to the beach. Cafés and restaurants near by.
Communication during our stay as well as for check-in and -out was nice, fast and super easy.
We would definitely come back again!
