Look no further, Casa Serena is awesome. Alessandra and her daughter are the kindest hosts you can ask for - they really treat you like family! As for the listing, it's pretty much in line with the description. The room is comfortable for 1 or 2 people, and the rest of the apartment is really nice and cozy. The location is phenomenal - 30 secs walking to the Gran Via metro station, and walking distance to just about anything you'd want to see, eat, or drink in Madrid. Next time I'm in Madrid, I know where I'll be staying.
