I stayed at Raul's place for two and a half months, and I totally recommend his apartment, especially for long-term stays. Raul is a kind, easy-going and cheerful person, and he made me feel at home. He helped me settle down in Madrid (getting a metro card, getting to know the neighborhood, bus stations, etc.). He also provided me the privacy when I had to study in the evenings. Most importantly, Raul was careful about Covid-19 and took the necessary precautions, which made me very very safe, and I thank him for that.
The apartment has any utensils you may need like the microwave, the dishwasher, the laundry machine, and the kitchen is well-equipped. A cleaning lady visits the house regularly, so the apartment is always clean. The room is perfect for a single person with a comfy single-bed, clean sheets, a heating system, enough storage space, and a great view of Arriaga Park! The shared balcony also looks over this lovely view, and I really enjoyed having a coffee or beer on the balcony. The only thing the room lacks is a study desk, but it was not a problem for me as Raul kindly shared the table in the living room when I needed it.
The location is also great. It takes approximately 50 minutes to walk to the center and 30 minutes with public transportation. The neighborhood is well-connected with the rest of the city with the Metro Line 2 (La Almudena or La Elipa Stations), Metro Line 5 (Quintana Station), and busses (28 and N9) which are within 5 minutes walking distance to the apartment. Getting there from the airport is also very easy using the Metro Line 5. There are lots of supermarkets (Lidl, Ahorra Mas, Dia, PrimaPrix) and local grocery stores around the neighborhood, as well as bars, restaurants, or any kind of shop you may look for. It is a lively area and is very safe, both day and night.
Overall, I really enjoyed my time at Raul's apartment, and I am glad that I chose his place. I recommend his place for long-term stays, but I bet he is also a great host for short-term guests too.
