A good air b&b in the heart of Madrid, the room is slightly smaller than I expected but nevertheless has everything you need; a well sized bed, air conditioning, washing machine, TV and cooking facilities. The bathroom is a bit on the small side but everything is in good condition and clean for the price, I would say above average for this price range. As far as cooking facilites go, there are two stoves and a fan but no oven which was troublesome at times when I wanted to cook certain foods.
The location of the apartment more than makes up for this however. It is in the heart of city just off Gran Vía, which has a huge number of shops for everything you might need. The corte inglés is also very close, as well as El Retiro and other famous Madrid spots and museums. The closest metro station is about a 3 minute walk, as is the closest supermarket, so the apartment is well connected to the city. I would recommend this airb&b for no more than 2 people, any more and I can imagine the slightly smaller size of the apartment becoming an issue.
The owner that I met was very friendly and responsive, provided excellent customer service and was on hand to answer any questions I had. Overall, a great little airb&b in the middle of the city, would be great for a couple or for a solo traveller!
