I've stayed in 8 fifferent places on the island. The only inconvenience was this one.
Raphael, Things to improve:
When you call and a guest points out that today is not the check in date, don't just hang up on them. Apologize and tell them you look forward to seeing them soon. When a guest calls for diections to find the apartment from already unclear directions don't say you'll call back. Nobody called back. Be prepared to communicate directions.
Don't tell guests they should change their profile picture because you think they look better. Eww
When a guest says the apartment gets cold at night don't avoid the issue by saying it gets warmer during the day.
When a guests points out again that the apartment is much too cold and the space heater has no affect do something about it rather then have a good laugh about it.
Do invest in some or any decorations. The apartment looks like moving day just finished.
Don't start the landscaping machinery outside guest's bedroom window at 8am. I didn't magically guess you were outside there.
