Place is very good for 1-2 people. Comfy bed, big bathroom, table with 2 chairs and an armchair with coffee table. Little kitchenette equipped so you can easily order food and make it warm again. A/C works fine.
Unfortunately, the apartment is located in a sketchy neighbourhood. 5 mins walk away you can find a metro station Tirso de Molina and many great restaurants, bars and cafes, but just outside the window, there is a little square, beloved by nutorious people, offering drugs and using it as a restroom (or maybe dogs, but I doubt that). Loud music from early morning, fights and screams at night. All that happened during each of 3 nights I spent there. Many times I didn’t feel safe. The walls between apartments are thin, so you can also easily hear your neighbours, that could be loud at night.
