This is a superb, comfortable and well-equipped apartment where we had a great three weeks. The location was perfect for us because very close to family we were visiting in Barcelona. But I can thoroughly recommend it to anyone who doesn't feel the need to be close to the centre - and Sarria is a lovely area in which to be in any case, with food shops, cafes, restaurants in an old village now a prosperous suburb. Travel to the centre is very quick on the Metro (5 minutes walk) or bus (opposite the apartment building).
We were always amused that the heading for the apartment on AirBnB says 'free Nespresso!' but that wasn't the case anyway. We weren't in any way troubled by the fact that it wasn't there (though a machine was) but it might be taken off the heading! This is not a serious issue and the apartment is exceptional.
