Marlen was very sweet . As soon as i booked the apartment she mailed me a list of places we would like to see around. She was waiting for us at the apartment at the time we were supposed to reach..she made us comfortable and acquainted with the apartment. The house was exactly shown in the pictures. She had all the necessities like washing machine ,microwave TV, etc arranged very well compared to the size of the apartment. I would give a 10 on 10 for the cleanliness..I had read reviews saying that ther is too much noise to sleep on the sofa as ther are pubs and restaurants downstairs . Well!! We dint mind it so much. We found it very lively..And with no doubts Madrid is a place to enjoy the night life ..!! Her place was very close to the major tourist areas so we could walk and reach everywhere. Marlen also booked us a cab to airport as our flight was early morning. The building and the surrounding area was safe but its near a red light area..but that goes for the whole of central area of Madrid.. So i would advice taking a cab in the night. Overall she was a genuine, helpful and a perfect host as I had expected.
