My wife and I stayed at Charlotte’s place with our toddler for almost 2 weeks and we were more than conformable. The kitchen and bathroom are on a separate level which makes the apartment much bigger than it shows online. We were also pleasantly surprised with the size of the bedroom, we had more than enough room for the pack play. The place was spotless and kitchen/house loaded with all things we needed to be comfortable during our stay.
Additionally the location is amazing. The house is about three blocks from some really nice restaurants in a really safe neighborhood. It is also close to to the Capital Crescent Trail (which is a beautiful paved path next to the Potomac river) so we were able to take a lovely 2 or 3 miles "hike" down the path with the stroller to the Georgetown waterfront (There was also a Capital Bikeshare Station close by which you can rent bikes from and ride down the trail)
Overall, great apartment, great host, great location, great stay. Highly recommend!
