The photos no longer represent the current state of the apartment. Everything is very worn and, for our stay, very dirty. There were crumbs and food stuck to the couch and when looking under the cushions for a misplaced phone, more food and filth. It needs a deep, deep clean, fresh paint and some relatively minor fixes to the shower handle (it falls off when adjusting the water temperature) and the front door lock (part of the latch is unattached and falls off upon opening). Some of the floor in the kitchen is very soft and needs to be stabilized. The walls and furniture have scuff marks and stains that could be easily cleaned.
The good: the location is super central—great for a short stay in Madrid, the windows are remarkably good at blocking the street noise and the apartment gets great light. Alicia was very professional and check-in/checkout were easy. Our stay was super short, just 36 hours, so we did not contact Alicia about correcting the issues.
With some minor renovations, proper cleaning and maintenance this could be a nice place but our experience was lacking and I would not repeat.
