We had a great stay at Carmen's apartment!
Location: less than 5 minutes walk from Cristo de la Epidemia bus stop, where you can catch three lines to the touristic city center (about 10 minutes) and further to the Maria Zambrano train station. You can also take a 15-20 minutes walk.
Apartment: recently renovated interior - very clean and fully functional kitchen (w/ washing machine) and bathroom. Three bed rooms not only had windows but were also equipped with ceiling fans which were really nice to have for hot August nights. The apartment is on the 6th floor but there's a lift that it was no problem for a family with two kids.
Communication: everything went very smoothly - Carmen always wrote to us in Spanish but the content was always clear; we always replied in English and it was all fine. They were also kind enough to give us a ride to the airport early in the morning! (about 20 minutes)

We were lucky to find this apartment in a popular summer holiday destination, and we highly recommend it!
