Diego is incredibly responsive to our requests and was able to accommodate us on short notice.
I echo much of the same feedback that Krystal stated in her October 2018 review: the front door is a bit difficult (fortunately my partner was able to manage), the bathroom toilet seat is smaller than the toilet bowl and is a bit wobbly/the seat cover doesn't stay up, and the shower is a little weak. Diego is working on improving the apartment-- you can see light fixtures waiting to be installed and he mentioned the second room is being fixed up. We had an issue with the hot water, but Diego did everything within his control to remedy it. Thus, as Krystal mentioned, Diego was so responsive which made us feel mostly positive about our experience.
That being said-- for the price (at the time of our booking), location, and the fact that you get the entire apartment to yourself... it's a good deal!
