Stayed for 4 nights.. room #2 is perfect for 1 person (big closet + hangers) although the streets are loud at night however that's the charm of old Madrid.. and enjoyed it! Location is great! Everything's within a walking distance of 5 to 12 mins ..
The place is clean and comfortable . You have everything you need ..kitchen... laundry room ect.. the first bathroom needs a little fixing but not a big deal ..
I will stay there again for sure!
