We stayed 5 nights in Leo's apartment and it was very nice ! We were 5 friends and the size of the apartment is perfect. The bedding is very comfortable, there are two bathrooms and the living room is bright, well decorated and the apartment remains quite cool even in a heat wave. The situation in Malasana is perfect in a street very quiet but near to the center, the bars and restaurants. We visited Madrid by walking only.
Furthermore, our plane arrived very lately and the son of Maggie waited for us, very kind of him !!
I recommend !
