Apartment was wonderful, a good space for our family, clean and well kempt. We had a two bedroom apartment for 2 adults and 2 children. There was a sofa bed in the lounge which would have allowed an extra 2 people to stay. I expect the apartment would feel cramped with 6 people. The location was excellent - a short walk to Sagrada Familia, the metro station, restaurants, cafes, small supermarkets. We booked continental breakfast which was delivered to our apartment every afternoon for the following morning. The staff were really helpful and easy to contact via business WhatsApp. Ability to leave luggage at their central offices if you have an early or late transport from Barcelona. A small rooftop pool at the apartment block - which has a beautiful view over Sagrada Familia. Pool would be great in the summer but a bit cold in October!
