I stayed in Rosaria's Apartment in Madrid for four days and I really enjoyed it.
Rosaria is a really good host, she is so friendly and nicely. She gave me many great Tipps.
From the Apartment is nearly everything accessable on foot. So a perfect location :-)
Everything looks like on the pictures. The furnishing is stylish and homely.
All in all I would stay there again, so I definitely recommend Rosaria and her Apartment.
