This is a great place, large and comfortable. We were 5 adults and one kid. The location is unbeatable, two blocks from
Plaza Mayor and really you have most of Madrid’s attractions from 10 to 30 mins walking. The neighborhood offers lots of convenience stores, cafes and restaurant. La Latina subway is rite across the street and the Cebada Markets - half block away- offers great fresh products in case you want to cook.
Also the appliance and Barth room were pretty new and food quality. Makes you feel in a clean and comfortable place.
I guess the two improvements would be to provide cooking and cleaning basic items such a dishwashers detergent, salt, tea, coffee, oil, toiletries. Also, check in could be more automated like in other places in Europe were there are keys available in a lock or using an app.
I will stay here again.
