We were 3 Girls who did a Weekend trip. The Flat is near a Metro Station, only 3 Minutes walk. This was perfect! The flat is very clean and everything you need is there. You feel very home there. The key handover went well and very fast, so easy! They gave us Tips for the city and told us where to go for the best Tapas :-)
Take some shoes with you to wear in the flat, because the floor is very cold. The noise in the Room with the two beds was quite loud, there was a construction in front of the appartement, it was a little bit disturbing.
Over all we had a great Trip in Barcelona in a really nice flat!
