Maria is a wonderful and caring host. Any questions we had were met with quick replies, even early in the mornings or late in the evenings. Her English is impeccable, so communication was a breeze.
The place was tastefully decorated and very clean. The pictures do it justice. It felt like we were among the first to visit.
A couple of tiny details from a picky person:
1) I recommend you bring slippers or warm socks. The floors are of stone and hence (in the beginning of April) a bit cold. No floor heating is available. Also, dangerously slippery when wet.
2) The key that locks the apartment door has to stay in the apartment to enable the electric circuit. Meaning you can't expect to load your batteries or run the washing machine while away.
3) The apartment door has a small gap between the floor and the door. Less than half a centimeter, but some noise travels from the hallway.
All in all, it's a superb apartment that I'd both recommend and stay at again.
