We enjoyed our stay at Sean's place. he was always very responsive and helpful with us. the apartment is quite spacious with a well equipped kitchen and a very welcoming shelf with information about Washington.
we didn't find the location to be good, since it is 25min walking until the capitol and the only public transportation next to it, is a bus which will leave you 10min away for any point in capitol Hill, so you will need some time to get to the main attractions.
There was also a very loud AC next to the room (probably from the neighbour) running all nicht long which disturb in some way our sleep.
Otherwise it was great!
