The flat is just amazing. It is very spacious, decorated with perfect taste and without any clutter so that you will feel instantly at home.
I loved the high ceilings, the very practical cut of the flat and the artwork here and there.
The area is just perfect for anyone who is into art - all the museums are at walking distance and the street where the loft/flat is located seems to be a hot spot for galleries (i was there by chance during madrid gallery weekend and did some gallery hopping).
5 min walking distance from Atocha main train station (ideal for a day trip to toledo) and 5 min walking distance to Buen Retiro park (ideal for jogging or chillout)
Lovely restaurants around the corner.
The flat is clean, and the host super responsive.
I can only recommend!
