Very clean, well equipped flat. Very comfortable beds - we used 2 of the 3 bedrooms - and excellent location - 10-15 mins walk to metro and we ate locally every evening in small local bars and restaurants. We felt part of the local community.
Cristina was welcoming and supportive.
With windows open there was a fair amount of street noise late evening and in the mornings and in the second bedroom there was some noise from other bathrooms and lift. Also not much natural light in 2nd and 3rd bedrooms. It was a good and comfortable base for going out and about in Barcelona and with earplugs we slept very well.
