The Montse's place is amazing! We came to Barcelona to celebrate my birthday with three other girlfriends and we all absolutely loved it. The location is perfect, walkable to most of the places you usually want to visit. Very nice balcony where you can watch the nightlife before you go out:-) a lot of shops and restaurants around the flat, easy to reach from the airport. It was big enough for four of us, but we are very close friends. ( the place is not very spacious but cosy) Whats probably the best about this place is the atmosphere. It really felt like we are living in Barcelona not just visiting. Honestly can highly recommend this place.
