We've just spent 5 great days in Maria's apartment.
Maria was not on hand to meet us but she arranged for a friend to do that job for her. Despite this, she maintained close contact with us before and during our stay to make sure that things went smoothly.
As far as the apartment is concerned, you really could not ask for more. It's actually bigger than it appears in the photographs and is very well appointed and to a high standard. If you want to cook (unlikely), the kitchen has everything. And the bathroom is great too.
The location is superb. It faces inward from the street so it's very quiet. The beach is at one end of the street while a good supermarket, the old town and short walk to La Concha starts at the other end. There's also a great fruit shop a few doors down which always seems to be open.
We highly recommend this apartment for its location and for its comfort value.
