Nice, comfortable apartment in the heart of the city. The place is very bright and spacious, comfortable for a couple. Washing machine, microwave, toaster and coffee machine make it very functional (though I wish it had some additional cooking utensils, such as a good knife and additional pans). The apartment was SUPER clean. You can walk virtually anywhere in Madrid - very close to hip restaurants and bars in Malasaña and Chueca, and shopping in Gran Via or Sol. It's also incredibly quiet :)
Overall a great stay, I would come back. Thanks!
