Better check-in instructions are needed. We looked around for 30 mins and the coordinates provided were not accurate :/ A basic shower curtain would go a long way. A hook for the shower to stay up would be helpful. Better wifi and able to use it in the bedroom would be nice, same goes for An air conditioner in the kitchen and/or bedrooms. Make the space at the top of the stairs more private and usable.
The fridge makes a loud noise and is very old, replace it. Get rid of the oven and then you could actually hangout in the kitchen
