Excellent communication from the host about check in and check out. Also, the apartment has everything that a traveller on a budget needs: a lot of bottled water (like a case), some instant ramen (if you want to see stuff and not spend time at restaurants), washer and dryer, as well as some utensils and food in the fridge. It even has a nice kettle, which I was really happy to find!
The host leaves nearby and can help if you have any issues that require personal attention. Also, all replies in the chat were almost instant.
