Elstead is a wonderful host. She was already there when we arrived. She told us everything we needed to know. Her apartment is well equipped. We even cooked there one evening. The location is nearly perfectly situated in a pedestrian area. You have Gran Via on one hand and the scenic district of Malasana on the other, so that you can explore everything by foot. From the airport it takes roundabout 40 minutes by subway to get there with only one change at Nuevos Ministerios. The apartment is located in the 3rd floor (elevator is available), it has two windows, each with a small balcony. It is bright and although it is quite noisy on the street with all the people outside, finding sleep at night caused no problems.
We can highly recommend Elsteads apartment and would definitely stay here again if we come back to Madrid. Thank you very much!
