David was very helpful and we were able to communicate with him easily when we needed. He is an excellent friendly host. The apartment is very spacious and modern with cool decor and a balcony. Excellent location in Gràcia, a quieter village-like area away from city centre but easily accessible via 2 metro stops, Joanic (5 minute walk) and Sagrada Familia (10 minute walk). You can take the yellow line from Joanic to Selva de Mar if you want to go to a less touristy beach. There are plenty of restaurants/bars in Vila de Gràcia to enjoy which has a lively atmosphere at night. I would recommend Gola Taperia. We stayed the 3rd week in August during La Festa Major de Gràcia (200 year anniversary this year) which made the experience all the better as you can wander through the beautifully decorated streets and get a taste of local life. Would definitely recommend David's apartment for an alternative experience to city centre.
