Eloisa is a very nice person and very reliable. We were even allowed to stay longer than the actual check out time because our flight back was in the evening. Her hospitality was great in that regard.
The apartment is located perfectly even it it pretty small and there it not much light (windows). The cleanliness of the bathroom could have been better. the second little bedroom is pretty small and you hear noise and sound from the next door apartment when they use the bathroom.
But for a short stay I can recommend this accommodation, because it is perfectly located to explore the city of Madrid.
