We very much enjoyed our stay at Joseph's apartment in Petworth. It is modern, clean and just the right size for two people.
In terms of location, it is about 40 mins into central Washington DC (including walk to metro) which was fine. It is also not too far from a large Safeway supermarket and several restaurants and bars.
We found check in and check out very easy and Joseph sent us detailed information about the apartment, the house rules and the surrounding area.
Ideal for a couple wanting to explore Washington DC.
