623 was exactly as advertised! The location was perfect! Even in the chilly temps, we still walked to Union Station where we caught the Metro. There were 4 of us, but, it didn’t feel that cramped. The layout is nice and it is decorated with a contemporary flair. The Keurig was a lifesaver in the mornings! We never met the hosts in person, but, they were very responsive and loaned one of their own electric heaters.
