I had my own bathroom with shower in my room, air conditioning (I did not use it, there was no need), street blinds on the windows facing the street. There is an opportunity to iron things, there is a small shop with small things in the lobby, a microwave, a kettle in the room, and they even brought a refrigerator to me at my request!
It is located between two metro stations, 3-4 minutes on foot to the nearest one, near a supermarket, the area is full of cafes, pizzerias. Do you want to see Madrid? Just leave the hotel and go left, cross the whole city!
For a budget trip, this is what you need!
