We were thrilled with the apartment. The location is fantastic - we loved the charming neighborhood and convenience of the metro across the street. We walked all over centro from this spot and loved our own neighborhood (Huertas). The bookstore around the corner is so lovely! The little family run Italian joint Il Piccolino around the corner was amazing, too. And Brown Bear Bakery for bread, croissants, coffee and cakes! Even the panadería across Atocha had a great donut. There are so many options on small streets in this area.
The apartment is perfect. The beds are large and comfy, even the sofa bed. We cooked and did laundry. The washer/dryer (one machine does both!) was hard to figure out any particular settings. We just started it and let it go. Took three hours per small load because it also dries. There is probably a setting to just wash but we couldn’t figure it out.

There is street noise but not loud music and partying. Traffic and voices. I am super sensitive to noise and it didn’t bother me. You can’t hear it in the bedrooms.
The shower is large and the water pressure was fine.
The building has so much charm! We loved returning here. It felt specials.
Madflats customer service was very helpful via text for the whole stay.
We would return and fully recommend!
