I stayed at Sean's place while attending a conference in DC. It was a great place to come back to after being out all day. It felt very homely and I loved how Christmassy the outside was decorated! Everything I needed (and more!) was in this apartment, so it really felt like coming home.
I did not meet Sean in person, but check in/out was very easy and communication was excellent. Only downside was that the noise from upstairs carries and the AC/heating fan. Nothing that a pair of ear plugs couldn't fix! However this did not detract from what was a lovely stay :)
