I stayed at the property with my son for three nights. The location is superb, close to a great selection of restaurants, cafes and bars, easy to get to various forms of public transport, and a ten-minute walk from Plaza Mayor,
The property worked well for us - we did not spend much time there but it was comfortable, seemingly newly decorated and had sufficient but not excessive furniture, cutlery and equipment.
It’s a reasonably small property with a bed area overlooking the main seating / dining area and kitchen - in this area the ceiling is quite low so sitting up in or standing up by the bed needs to be done carefully!
As the property is in a block you can hear some people walking around but there was no loud noise. The listing mentions that there is little light, which is true, but again that didn’t affect us.
I’d say that the property is very functional and makes the most of the space it is in.
