Arc House was a bit difficult to find. The address takes you to a sign on the street. When you make it there, you must look for the door with an Arc House door bell, ring it to be let in, upon entry you will find another door to ring for entry. Once you make it there everything is simple. It's a great location for city touring and close to the metro. Also the place was clean and the people were nice. Thanks Arc House for a lovely stay.
