We had some communication problems (on both sides!) on arrival for a late check-in - we couldn't access the airport wifi to use whatsapp and let our host know that our flight had been delayed, and the person meeting us couldn't respond to messages from international numbers - but we made contact from a bar with wifi near the apartment in the end, and managed to get in. Our hosts dropped off a bottle of cava to say sorry next day, which was nice of them, and they were ready with helpful advice at all times. The neighbourhood of Gracia suited us well: unlike the streets below Placa Catalunya, which teem with tourists, Gracia still has a funky neighbourhood feel, yet it's not a big deal to walk or Metro down to the tourist sights from there. The apartment is compact and stylish, although it has endured a little wear and tear from young party animals in places, and is well equipped with guide books, a Spanish dictionary etc. Two squares in the immediate neighbourhood make for a pleasant evening experience, and special mention must be given to the restaurant Pepita, a few minutes' walk away, which entirely lived up to its Trip Advisor raves, and was thoroughly worth the wait to get in. Overall, recommended!
