Mercedes is the most welcoming host I've come across. Her dog Stevie (who's actually a rabbit) ;) is super friendly as well. She prepared breakfast every morning and made fresh coffee. In the evenings she usually offered some home made sangria (best tasting ever), wine and even champagne... She also gave us advice on what to do and see int the city which was great.
Her apartment is beautiful and charming, and the view from the terass is hard to beat! We enjoyed breakfast and evenings there a lot! R2 was just big enough for for us traveling with our baby. It has a lovely window just above the bed with flowers just outside.

The blocks surrounding the square had all you could need. We got a mini tour from Mercedes where she pointed out things like; a price worthy supermarket and a really nice café (Oviso)
There also the the beach just 20 min walk away which I can't recommend enough!
