Marco was very welcoming and kind. The communication was easy. The apartment was within 20 minutes walking distance from Joaquin Sorolla with groceries stores and a few cafes nearby. City center was 40 minutes walking (nice walk though through the green riverbed), the beach 30-40 minutes by metro/bus.
The room was superficially clean. However, the apartment is not in good condition at all. The kitchen was quite dirty and there was a lot of mould in the shower. Even if the price was not too high, I think an apartment/room like this should not be rented out before getting a serious cleansing.
