I stayed for 4 days to attend a conference held in the Washington D.C. The hotel facilities were clean and all the facilities were satisfactory. In particular, the shuttle from Reagan Airport to the hotel ran from 5:10 AM to 11:40 PM, so it was very convenient to go from the hotel to the Reagan Airport subway station every day and then take the subway to downtown Washington. In particular, on the last day, I checked out at 2:30 AM and went to the airport. I called a taxi, but it didn't come for an hour, so I was very flustered. My flight was at 5 AM, and I was worried that I might be late for the departure time, but the person working at the hotel desk (I don't know his name, but thank you) called an Uber taxi for me, so I was able to arrive at the airport safely and return home. The people working at the hotel were very kind, and the facilities were clean. I would like to thank the people who worked there (at dawn on December 12th) again.
