What a lovely AirBnB experience! Nicolas was communicative and helpful from the minute we booked the trip. Check-in instructions were sent well in advance. He provided a number of fantastic recommendations for the neighborhood and city. He or Cesar always responded to our questions well within an hour or less and dropped off anything we needed. We had a hot water issue one day, and they had it investigated and fixed the same day while we were out and left us some goodies. We couldn't really ask for better hosts!
The unit was very clean. The bed was super comfy and luxurious. We felt super safe; the doormen and neighbors that we met were lovely. The cafe downstairs was fantastic!
Since we were there in January and there was no heat, the apartment was colder than expected, but they provided additional blankets promptly when we asked for them. Also, the apartment does not get a ton of natural light and was darker than we expected from the photos, so be sure to set an alarm in the AM :)
