The flat was really wonderful and cozy, we stayed over Christmas with my family, and it was all perfect. At the check in we got some really good advice on what to visit in the city and how to get around. The flat was fully equipped with everything and we could cook some nice dinner in a perfect way. The heating was working perfectly as well. I would really recommend Marta's flat if you want to stay few nights in Madrid and enjoy some relaxing time in the evening at home.
