This was our first experience with Airbnb and Ernesto's apartment was great. He was very prompt answering all my questions and his brother Antonio was also very nice & patient with the key handoff as our
flight/airport exit was delayed. The apartment is centrally located very close to Plaza Mayor and for our purposes it worked. We walked most of the time but Metro stations and the bus are all within steps of the unit. Plus a supermaket, pharmacies & lots of places to eat all very close by. Everything was very clean & organized and the unit is pretty spacious for 4 adults & a toddler.
We live in a city in the US so the street noise never bothered us but be aware that there are lots of cars & people around at all times. The only negative thing I feel I need to mention is that the second bedroom has no A/C unit or ceiling fan and I wish I would have known before booking. The room gets hot and the only way to cool it is to leave the A/C on from the living on all night & the door open with no privacy.
Overall great location & convenient apartment in city center.
