I've stayed in over a dozen AirBnBs in several different countries and this was by far the worst experience I've had. We booked Jacobo's place for 6 nights and checked out after 2 to stay in a hotel. Details:
The apartment was a bit dirty, with dust and stray hairs on the floors and carpet like it hadn't been truly cleaned in a few months.
There was a serious leak in the roof so we had to put down a bucket to collect water.
The hot water heater worked for 10 seconds before beeping and turning off, and smelled as though it was leaking gas.
There were biting ants all over the apartment (and a warning sign in the apartment about ants, despite hearing nothing before check in) including in the bed, and we got many bites.
You have to climb a two story, extremely narrow circular staircase to reach the apartment. It felt dangerous for two people in decent shape in their 20's, so be very careful if you have mobility issues. You also cant bring up full size suitcases (larger than carry on size).
The apartment had long term construction going on next door, which started early in the morning. It's also directly in the airport flight path and planes are very loud flying overhead long into the night. There is no insulation so it is extremely loud.
We have requested a refund for the nights we didn't stay because of the poor conditions and Jacobo has been unresponsive. We're currently working with AirBnB to resolve :(
A positive: The apartment is in a great location and the neighborhood is beautiful. If you can find other options in the area I would definitely recommend!
