There were a couple of items that would make his place better. The window A/C unit must be updated to a more robust and energy-efficient unit. The drapes kept creeping open because of the window a/c. Velcro would remedy the problem. The refrigerator had some things left from a prior rental. I talked to Daniel about these concerns, and he was very receptive.
Will I stay at Daniel's place again? Yes! Not my first choice because of the abovementioned concerns, but for the price and location, it gets an "A." I have stayed at multiple apartments in Rio.
