Nice cute cozy appartment, ideal for a few days stay if your main goal is to explore the streets of Madrid. It was very hot outside, but inside was pleasant since it's partly in the basement. The area looks a little sketchy, but it's totally fine during the day, as there are plenty of people on the streets. I would maybe not recommend for solo lady travellers at night. Other than that the place was clean, enought towels and bedding, shampoo, kitchen supplies, close to all city center attractions. The self check-in and check-out went smooth, at first the instructions looked complicated, but when you are there, you will understand everything and it's easy. Great value for the money.
