My friend and I both strongly recommend Jeffrey's! We wanted to be close to town but at a lower cost than being directly on the mall. This place is exactly that! Access to the Metro was incredibly close, and we had a very easy time getting to and from restaurants and sites.
The place itself is exactly as advertised: it has tv and internet and a full kitchen as well as room for 3. I agree with a previous reviewer that it might be especially ideal for a couple or for a couple plus one. We ended up with just the two of us and ended up switching: one of us in the bed one night and one on the fold down couch and then doing the reverse the second night. The fold out couch isn't amazingly comfortable, but we each got a full night's sleep on it!
I really, genuinely have no complaints here. Our stay was easy, clean, and comfortable, and Jeffrey was a great host who kept in contact when we needed him!
