Sergio's place was great. Close to public transportations, Plaza Mayor, Palace and etc. It easy to get around by foot. Lots of shops, restaurant, malls around. He is very easy to reach and very informative. Sergio had maps, brochures about Madrid (places and things to do), it was very handy for us. The place is exactly what it looks like, very clean, full of essential amenities, lots of foot traffic outside and very safe neighbourhood. Overall, we enjoyed our stay in Madrid. Will keep in mind this place when we return to Madrid.
