I recently spent 5 days in Arturo's apartment, and had a lovely stay.
The apartment is very comfortable, with a comfy bed, good shower, and is quite spacious for a studio.
The washing machine works well (there is a communal dryer in the basement), and the kitchen appliances were of good quality. As previously mentioned, there is just basic kitchen equipment, but more than enough to cook yourself some meals, although you are spoilt for choice with restaurants in the surrounding area. There is a lift to the 5th floor apartment for those with heavy bags.
The area where the apartment is situated was great, very safe to walk around, a supermarket 2 blocks away, and was quiet at night.
The nearest metro was about 10min walk from the apartment, with good connectivity links to the rest of the lines, and the city center 20-40min ride, depending where you wanted to go.
The communication with Arturo was excellent before and during my stay. Check in information was clear and easy to use, and he was very quick to respond to any messages, including any queries.
Overall a great Airbnb experience, and would recommend this apartment.
