Carmen is a very kind person. She is very prepared to be a perfect host. She welcomed us personally, leaving us a small map (done by herself) with the most important places to visit and restaurants to go to. She also positively responded to our request to borrow us some beach towels for one sunny day.
The appartment has many nice vintage elements, that show how much care does she put into it. It is a pity that the bathroom is a little bit dated, but it is just a tiny detail.
It is very close to the city center. You can either go by foot or take a bus that takes you to the most important sites, or to the Alameda train station (where the airport train arrives). We had a rent car, that we could park on the two closest streets (Calle Fernando el Catolico, or Calle Cristo de la Epidemia), but is is not easy at all to find free place.
We strongly recommend it.
