This spacious, well-furnished and illuminated 3BR, 3 bath apartment overlooking Sta. Ana Plaza could not be any more comfortable nor conveniently located to tour Madrid. Given its prime location, it is nevertheless quiet, especially in the master bedroom and second bedroom towards the back to the apt. The bathrooms were big and showers very nice in each one.
There are two very pleasant couches in the living room adjacent to a large dining table, which accesses easily a well-appointed kitchen. Our only struggle, as Americans not familiar with some brands of European appliances, was figuring out how to turn on the stove, but we made do with the microwave and the electric hot-water heater, plus the excellent expresso machine (and since we didn't plan to do any major cooking, we didn't ask the host company, MintyHost, if they could help us figure it out).
Minty host, who manages the apartment, have their offices just a couple of minutes away from the apt. They were extremely responsive and helpful; and with almost 200 rental units under management, they have a large cadre of staff, cleaning crews and so forth.
The beds were all very comfortable with nice pillows and a clean, new feeling bath and hand towel on each bed upon arrival. The place was also very clean when we arrived, and provided a perfect complement to our hotel lodging in three prior cities of Spain that we had visited. And after 10 days on the road, having a very efficient washer/dryer (which combined the two functions at one flick of the dial!) was a nice touch that spared us a trip to the laundromat. While not inexpensive, it is well worth the price for its location, comfort and up to date amenities.
