We were 2 adults and a teenager and stayed for 10 days. The apartment is very comfortable and spacious, it will perfectly accommodate 5 people. The neighbourhood is safe and short walking distance to Sagrada Familia, Passeig de Gracia (if you like to walk like us, most of the attractions al less than 30 min walking) . It has supermarkets, cafes, bars around the corner. It is quiet at night which is great. Amenities are great, bed is comfortable, bathroom is big, hot water works perfectly, washing machine (great if you travel light). Very easy to get from the airport: you can take the Aerobus to Plaça de Catalunya and then a bus or just walk like we did (or take a taxi if you have many bags). Check-in was smooth, communication with the host is great.
