We enjoyed our stay in this apartment. The location is ideal - right on Puerta del Sol with a view of the plaza from the living room window.
Yet the bedrooms are away from the plaza so there was no street noise in the bedrooms.
The host met us within 10 minutes of our arrival and they were great in their communications throughout the process.
A very short walk to Plaza Major and all the shopping. We walked to most of the attractions we wanted to see. There was also a taxi stand half a block away.
It is downtown in an old city so expect an older but very solid building. There is an elevator that was ideal because the unit is fifth floor (floor 4- ground floor is floor 0). There is a large entryway into the building with an iron gate that is locked at night.
We were two couples in our late fifties. The beds were what you might except in a twentysomething’s apartment - but comfortable enough.
I would recommend this apartment.
