My wife, my daughter, and I stayed in Carlos' place for a week in May, 2022. It's an airy, two bedroom, one bath apartment with a good size living room and kitchen. There are many windows, letting in a lot of light and breezes, and the views are outstanding. WiFi works very well, the beds are comfortable, and the bathroom, though small, is modern with plenty of hot water.
Check-in was super easy and Carlos is such a friendly person. He's easy to reach with questions or concerns and he responds very, very quickly. It was quite hot one day, so we tried the air conditioner and found that it worked quite well. The location is excellent, as it's in a very interesting neighborhood and near metro stations and many terrific restaurants and bars.
As others have noted, the floor does creak and you can hear your neighbors walking above and some noises from the street, especially with the windows open. This didn't bother us, but if you're a light sleeper, you may wish to bring earplugs or download a white noise app.
We highly recommend the place and would not hesitate to stay again!
