Max's apartment is in a vibrant and lively neighbourhood full of restaurants, bars, cafes, shops, museums, and subway stations all within easy walking distance. You'll likely be able to do everything on foot for your entire stay in Madrid, which is the best way to experience the city.
The neighbourhood is loud late into the night on Fridays and Saturdays, so if you won't be out partying, bring earplugs.
Max is very helpful, responsive, and welcoming. The apartment is clean and comfy. We had a lovely stay.
