The modern, spacious and clean space was a great home base if you want to stay in the city, especially for an extended stay. The bed rooms were good sized. We highly recommend it-not your typical small European apartment.
Our hosts were communicative on the day of our arrival and throughout our stay and allowed us to get in two hours early. The apartment accommodated 7 people very comfortably for 11 days. We were able to do our laundry. It was easy for Ubers and taxis to pick us up right outside the door of the building. It is a few blocks from a small grocery store and we were able to stock up on food for meals in. The full kitchen was stocked with utensils to make it easy to make full meals.
The building itself was very quiet. It was nice to have a restaurant in the adjoining building, especially the day we arrived. While we could hear the diners outside two of the rooms at night that overlooked the alley where there were tables, it promptly ended when the restaurant closed at midnight. This is Madrid, a late night city, so if you stay in the city, this is a concern most places. The difference for this apartment is that the diners promptly left at midnight and after that the street was extremely quiet until 10 am the next morning. If you're lucky, you'll get to hear the amazing church choir rehearsing with the windows open in the building cross the alley as we did.
This apartment was close to the palace, shopping, restaurants, Plaza Mayor, Mercado de San Miguel, Palace, and Convent de Corpus Christi (where you can buy cookies from the nuns). There was also easy access to the Metro (subway) and buses.
We are avid travelers and AirBnB guests. From our years of staying in many places, we rarely would think of staying in the same place twice. But if we ever return to Madrid, we would definitely stay here again.
