I was having trouble opening the door to my room, but when I asked the cleaning staff, they told me how to open it easily.
The next day, the room smelled like sewage, so I had to take a cold shower to get rid of the smell. There was no coin laundry, so I went to one around Munich Central Station. It's close to the airport, but it takes about an hour to get to Munich Central Station. It's inconvenient for those who don't have a car. There is a bus nearby, but the number of buses is reduced on weekends, so it's recommended to go out on weekdays.
