Teresa and Santiago are both very nice and welcoming people. However, I wouldn't recommend their place. The bedroom door doesn't lock which is quite stressful (especially since the main lock on the house door doesn't seem very trustworthy). The carpeting isn't very clean, the kitchen, in which I went a couple of times just to boil water for my tea, is an absolute mess. Add to that that they had very loud guests over several times, and you'll guess I didn't have a very pleasant stay. This place is probably fine for a layover as it is close to both the city center and the airport (about 20 min from both by bus), but I stayed there for a whole week and wouldn't recommend doing so.
