Absolutely wonderful! Nelida (who lives downstairs in the house) is an exceptionally helpful and friendly host, offering useful local advice on trips, restaurants etc. She kindly loaned me a small day pack when I realized I'd forgotten to bring one, and giving me a string bag to use for the rest of my trip as i left. She also gave me a ride to the bus stop for my onward trip.
The room is lovely and gets lots of cooling cross winds. That plus the ceiling and stand fans are sufficient to keep you cool (although her other loft room has an ac unit, as does one of the downstairs rooms).
The mattress and pillows were comfortable and the room was clean, as was the bathroom (shared with the other loft room). The hammocks on the front and back porches are great for relaxation. The washer and dryer and kitchen (shared with Nelida and other guests) were really useful.
The house is in a real (safe) Belizean neighborhood, a 10-15 minute walk (or a cheap 5 minute taxi ride) up the hill from downtown. This means birds, dogs, chickens etc. from sunrise, although I found the fan helped block that. It also means amazing cheap breakfast tacos from the stand at the end of the block, stew chicken and rice at the other stand down the road, etc. I much preferred this to staying in the more touristy accommodations downtown, especially with Nelida's warm and helpful company. Definitely one of my favorite Airbnb successes!
