Booking went smoothly from beginning to end with great communications from the hosts. We were late arriving but it wasn't a problem and Christina was waiting for us at the door.
Location of the apartment is good for Segrada Familia and Metro stops and bus are close by. However, it is a short travelling distance from the more central areas but not difficult. The road it's located on if however large and VERY busy and the traffic is noisy from early till late. We noticed the noise a lot in the 2nd bedroom.
The apartment is small but plenty of room with stylish features and everything was spotlessly clean. Plenty of facilities in the apartment, iron, washing machine etc. and the host had left some essentials for our arrival and some wine and bottled water as a gift. The main bedroom was large and the 2nd smaller but nice enough. Also, it has air conditioning which was a great as it was hot during our stay. We were visiting for a wedding but I would avoid Barcelona in the summer if I were to visit again. The apartment is on the 4th floor but there was a lift.
All in all a very happy stay even with disturbed sleep due to the traffic.
