I only stayed two nights as a solo traveler but felt right at home! Justina was very responsive and friendly and even helped me with some laundry! The wifi was fast/reliable enough for teleworking (room comes with a desk and chair), the shower had hot water with good water pressure, and I felt warm and cozy in the bed. There's a lot of restaurants/bars in the area, and very easy to walk around or take Metro. Would definitely return next time I'm in Madrid!
