Firstly, I can say that the apartment is exactly as described, clean, spacious and airy with fantastic views over the park. The roof terrace affords you a great view of the city!
Xavi and Luna are great hosts, always available to answer any questions you may have.

The apartment is situated in a quiet neighbourhood and the major attractions are within walking distance. There is a supermarket around the corner should you wish to cook in their fully fitted kitchen.
The Santa Catarina Market is about a 10 minute walk away, lots of fresh produce, meats, fish, shellfish etc…
The more famous Boqueria Market is about a 20 leisurely walk away, though to be honest, its full of tourists, and the prices reflect that.
Xavi is a foodie with a love of wines, and is proud to recommend local restaurants, wine/cava/vermuth shops, take his advice, he knows what he’s talking about!
The apartment is about 20/25 minutes from the airport and Xavi and Luna can arrange a taxi to pick you up from the airport, so you can avoid the taxi queues!
If you are planning a trip to BCN for the first time, or revisiting BCN, I 100% recommend this apartment.
