My two friends and I stayed here over the long weekend. Nhu was very helpful and responsive to and and all requests. The one main issue we had was with the temperature in the unit. The main house has access to the thermostat, but the guest house does not, meaning the guests in the guests house are completely at the mercy of the guests in the main house. For us, the downstairs was always cold (even with the space heater on) and the upstairs was incredibly warm. We closed the vents, opened the windows, etc, but didn't get to a stable temperature where everyone was comfortable- we were either sweating or freezing.
Otherwise, the place was clean. I would recommend you to bring your own body wash as the shower is only stocked with shampoo and conditioner. I would also recommend to the property manager that having the guest house guests take out the trash and put it on the curb is a little much to ask. If you have cleaners come anyway, I would say have them deal with the trash because it felt like we were encroaching on the main house guests when we went to the trash cans on the side of the house.
