Honestly - the least equipped rental I've ever stayed in. I was in Spain for a couple of weeks and rented 4 other AirBnb's across the country, each had its own charm, welcoming hosts, etc. This place was in a great location but other than that - it lacked in almost every way.
Kitchen - no cooking utensils, no knives (I cut my apple with a butter knife), no paper towels, no hand towels, no basic spices, no wine opener. There was a small bottle of olive oil.
Bathroom - no washcloth, there was a bottle of soap.
Bedroom - there were a total of 2 hangers in the closet
Additionally, the house rules pages referenced a "control panel" where all the things in the apartment could be controlled (lighting, heat/cool, music, etc). However, the hosts had removed it so I had to text them to turn up the lights, to turn down the heat. While they were responsive, this was absolutely ridiculous.
The positive thing about this space is the location. It is very convenient and, while very loud outside, you don't have to go far to see all the great sites in Madrid.
