We really enjoyed staying at Chloe and David's apartment. The location was perfect--we were able to walk everywhere, and when we didn't want to walk there is excellent metro access. The neighborhood is full of amazing bars and restaurants. The apartment itself is clean and cute, with more than enough space for us (it was just 2 of us, but you could have 4 and I think it would be fine). The pictures are very accurate. As other people have noted, there are a lot of stairs, but that didn't bother us. David and Chloe were also extremely friendly (we only met Chloe very briefly but she handled the emails and was responsive and helpful).
