This is the second time I stayed here, and I intend to stay here again in future.
The flat itself is wonderful and in a good location (quiet residential area close to many restaurants). Elena and Alberto are the most thoughtful AirBnB hosts imaginable, incredibly kind and welcoming. They're constantly thinking of additional ways to improve - while I was there they added a check-in guide with photos to their listing and a new sign to make it even clearer where to go; of course, it was already clear before - they're just going above and beyond :) Any information that you could possibly want is in their house manual. The items and little touches in the flat are all well thought out (USB charger, interesting books, decoration and household items that are actually useful) and the kind of things one would want to have in one's home.
Thanks for going far beyond what anyone could reasonably expect!
