José's place is perfectly located in the heart of La Latina, and a great starting point to discover the city, while being very quiet at night. You also have a Dia Supermarket and a great bakery at 2 min on Gran Via de San Francisco. For coffee or breakfast, I highly recommend Slow Café Madrid just around the corner.
Check-in was a breeze. The flat is extremely clean, and looks exactly as pictured in the photos. The bed is very comfortable and the internet connection is excellent. If you intend to use the flat for work or spend longer times indoors, the downsides I have noted are that it tends to get a bit dark during the day (the flat does not get enough light from the windows) and the kitchen is under-equipped to properly cook.
