Michael's row-house is located in a quiet safe area (Capitol Hill) close to the Union Station and all major places of interest (the Capitol, White House, Smithsonian museums).
The room is very clean, large and has all one may need (TV set, wardrobe, reading lamps). It was a nice surprise to see some paintings in the house. In the guest room there is a copy of Rothko's work (the original is on display in MoMa).
Michael is a great host! He patiently answered any questions I asked and provided me with everything needed (towels, toothpaste, etc). If I come to Washington DC another time, I will definitely stay at Michael's place if I have a chance.
