Thanks to Victoria and Carlos for the excellent apartments.
The apartment is small, but very comfortable for living ... I was alone, but if I consider it for a married couple, it is also quite comfortable. There is also a folding armchair) Minimalism, in white colors, comfortable kitchen with all the necessary options - dishes, appliances, stove, refrigerator, microwave, coffee maker, kitchen utensils. The bathroom is spacious, very clean throughout the apartment and fresh. The house has a laundry room with all accessories, a drying machine is very convenient. The owners give detailed instructions on how to get there by various means of transport from the airport. As for the location of the house - I think it's better not. All the important sights of Madrid are within walking distance, I have never used the bus or metro all the time. The railway station is also 7 minutes walk from the house))) and from there to any point in Spain on a comfortable train. I traveled so much to Toledo - 30 minutes by train. I am very satisfied with the accommodation of such hospitable guests.
Thank you, Victoria and Carlos.
