Small two-level apartment, first floor is kitchen/living space/WC, second floor is bedroom with shower.
Nice, clearń, well maintained apartment. Well stocked kitchen if one wants to cook for himself. Plumbing works perfectly (my small pet peeve), access is from the street through the clean inner courtyard.
Host answered very quickly (in Spanish, but airbnb translation works well for english-spanish) and gave all necessary answers.
Overall good value for money. Travelled solo and loved it. Location is well connected to public transport bus & underground metro (direct bus line to the Center, didn't try the metro).
