I am very happy I chose this house to stay in.
Space - big enough rooms. The bedroom has 2 matrimonial beds. The kitchen has a big enough dining table. It sits 4 people. The house itself is old but has a character and beauty. I loved the high ceilings and lovely Mexican decoraitons.
Location - right at the city center, a few minutes walk from Palacio de Bellas Artes and Alameda Central - a big park. The most surprisingly pleasant thing is that the house is very quiet. It doesn't have a front to the street, as it is above an internal courtyard. The city center is very busy and noisy. Having that not reaching the house is a huge plus for me.
Host - was very attentive, offered few times for me to contact him with any issue I may have. That reflected also on the details I found in the house - 2 umbrellas ready to be used (it was the rainy season), a hairdryer, iron, a folder with local attractions to see, and a local map. I was very happy also to have a standing fan.
Cleanliness - As I checked in, the host and two lovely girls (his daughters?) were very busy cleaning, so I got to actually see the level of cleaning. They did a very good job. I was a bit concerned about cleanliness, based on my previous Airbnb experience. This time I was very happy, the house was spotless.
Internet connection was good, with no issues whatsoever.
All in all, a very good experience, and when accounting for the price - it's a perfect deal.
