The apartment is in a great location, only 15 minutes walk from Atocha train station. The train station is linked directly with an express airport bus that leaves the airport about every 15 minutes and costs 5€. There are many restaurants and bars in the area and several supermarkets (Mercadona is less than 3 minutes walk). The apartment is close and easily walkable to many attractions like Retiro Park, Prado Museum, Royal Palace, and the Plaza Mayor.
The apartment is located in a secure building with an exterior locked door as well as the solid, lockable apartment door. It is super clean. It has a large comfy air-conditioned living room with a good-sized TV. We did not use this as there are plenty of things to do and places to see. There are two bedrooms which provides a great option in case one person snores. There is good lighting in the living room (great for reading), bathroom and bedrooms. The shower has good water pressure and there was lots of hot water. The kitchen is small but well-equipped with a full-sized fridge, stove, microwave, kettle, coffee machine, toaster, dishes and cutlery, as well as a washing machine. Wifi is excellent.
The hosts are very accommodating and responsive to messages.
Would we stay here again? Absolutely!
