It was a nice stay with Regina and Carlos. We stayed there for two nights, but were in the city most of the time so we didnt had much contact with the family. Regina was super nice and helpfull (we got food and coffe :-) ), we only had a bit of a language barier (we dont speak spain), but with some creativity and a translator app that was not really a problem.
The room we had was large and cosy. A small problem could have been that it had its windows to the streets and they are not soundproof, so we had the noices of the street. No problem for us, we also live in a big city, but if you are sensible to sound that may could be a problem.
We had a good time and can recomend to stay with Regina and Carlos!
