The host did respond quickly before and during our stay, so no problems from this point of view. For the money you pay, you get a big apt, located on a steep hill at the 3rd floor of a renovated old building, with a nice view from the living room. Be aware, this place is not for persons out of shape, but for the rest, you get used with climbing after the first day :D . The surroundings are safe and nearby there are some very good restaurants (I recommend restaurante Mili , but this is one of the several deserving a visit).
I also appreciated the possibility of self check in (since we arrived at night) and that at the last day, Sven found a way to keep our luggage after the check out (we were leaving at a very late hour). Overall, this place is a good choice.
