Absolutely perfect location and place! My wife and I are from Arizona so aren't familiar with mass transit. Shawn's place is a quick 3 minute walk to the U St subway and made for quick access to the tourist sites downtown without being surrounded by buildings. The neighborhood has a safe, inviting and quiet feel (we weren't kept up at night by traffic or city noises at all).
Onto the place... It is very spacious with ample room to spread out and relax. About every dish and cookware is available and we saved money going to the nearby Trader Joe's (3 blocks away) to cook at the house. What helped us a ton was opening the fridge and finding it fully stocked with drinks to help us transition before we could go shopping--that was a nice surprise! We used the dishwasher, and washed several loads of laundry and everything worked great. If you're tall like me, you'll appreciate the higher showerhead, too :-) The Wi-Fi was nice and fast.
Shawn was great and responsive to any questions we had. My wife and I loved our stay and would recommend it to anyone coming to D.C., especially to tour or spend time downtown!
