Excellent value for money! Just a small room but even with our big back packs and day packs we had enough room. The room is internal (still has an outside air window though) and is therefore pretty quiet. Comfortable bed and everything you need, although just basic and not flashy. Luis was super responsive and so friendly when we got to meet during the day for his daily clean. Kitchen makes home cooking easy. Hot, plentiful water in the shower and free basic toiletries. The only negative (which is not Luis' fault) is that the apartment itself is very noisy. The floor is made of pop-riveted squares and squeaks loudly when you walk on it and the doors (including communal bathroom) are also loud to slide open and closed. We felt conscious when getting up early or home late, that we would disturb the other guests, even if we were doing our best to be polite and quiet!
Otherwise we walked everywhere; great location. As such we thought that this room was exceptional value for money for this time of year. Thanks Luis!
Disclaimer: We also stayed 3 of our days in a bigger front room at Luis' place and found this smaller room to be better value overall and not so effected by communal apartment "noise" or street noise. We would recommend this room, especially for this time of year (cool weather).
