Carles is a wonderful host. In addition to using Airbnb messaging to contact Carles, we have also contacted Carles on WhatsApp. Establishing connection before hand ensured the ability to contact Carles while on the road to Barcelona. The location is within two blocks of Sagrada Familia. It is easy to hail a taxi or better still to download the MyTaxi App ahead of time with PayPal or credit card payment. Our experience with it is very good. Even for the ride to airport in the morning, the taxi came within a few minutes. It is possible to specify a minivan for the same rate.
The apartment is as described and shown in the photos. A supermarket is in the same block. Using taxis is inexpensive and avoids using public transportation. We arrived by a cruise ship in the morning and arranged with Carles ahead of time to drop off our luggage at 10 am, before the check-in time of 2 pm. It worked out that the previous guests had checked earlier than 10am and the cleaning ladies were there by 10 am, to let us in. If I had known about MyTaxi before landing on the port, I could have saved an hour of waiting in the taxi line.
Everything worked out very well during our stay, and Carles responded by WhatsApp promptly during normal hours. We definitely recommend this apartment and Carles.
