Carmen is such a nice person and her flat as well. The room is cozy and clean with warm decoration, and it's big enough for two person and their baggages.
It's very close to Atocha train station, subway station and bus station, you can go everywhere you want in convenience way. And you can even go to Retiro Park for sightseeing by feet. In the end, I sincerely recommend you this lovely place! Hope I will be there soon.
Btw I have to say that Carmen's three cats are sooo cute and approachable, when I hug any one of them, it's feels like hug soft cotton :))
