The apartment was very tidy and clean, well placed, near a metro station and with some good restaurants nearby. We had our own private bathroom, which was very ok for us. The room is very small, and it doesn't have natural light (has a sealed window) , but for this price it's very ok.
Carolina and Ivan are very nice, but we didn't interacted too much (they worked and we arrived home late every night) .
The wifi has a good connection, also the morning snacks were provided by out host (coffee, tea, muffins and Nutella)
Was a really nice stay for our trip to Barcelona :)
