Gaston and his wife Monica were excellent hosts. I genuinely felt that they did absolutely everything they could to make us feel comfortable there over the month we stayed, far more than any other host I've ever had on Airbnb. The flat itself is nicely decorated and lovely. It is a bit dark, just because of how the building is laid out, but there is plenty of lighting. In terms of location it really couldn't be more central, which is very advantageous for accessing everything Valencia has to offer.
