The apartment is in a very central location, close to all major sights and very close to public transportation. The building is secure and there is an elevator to the 8th floor. The street is very busy but the apartment faces the courtyard and is extremely quiet at all times. The beds were comfortable and the bathroom was clean, modern and very nice. The entire apartment was updated and is modern and clean. It is small, but was a great value for me and my teenage son. We had all of the space we needed and each had our own bed. The air conditioner worked very well and the apartment was cool even on very hot days. The host quickly responded to all of my communications and gave some excellent local tips for restaurants, drinks and day trips.
I would highly recommend this apartment for a stay in Madrid.
