We had a really nice stay at Carlos' apartment. His place is very centrally located, it is spacious, and has all the necessary equipment (bedsheets, towels, kitchen tools). You have to walk up quite a lot of stairs, but that didn't bother us. The only minor point was that the wifi was slow, but we reported this to Carlos and he said he would look into this. Carlos is very friendly, he gave us recommendations of things to see in the city, how to get there, and of nice restaurants to visit. We recommend!
