My wife and I stayed at Zeljka's apartment for 2 days during our brief visit to Paris. As the reviews note, the apartment is small, but accurately depicted and all you really need. It's also in a really great location if you want to spend a lot of time in the Bastille and Le Marais, and it's super close to a number of metro stops. More importantly, Zeljka herself was amazing. We asked her for recommendations and she sent us a TON of great info. She doesn't speak English, but we got by great on Google Translate, and she conveyed everything very well without the need to speak English. And she also provided a bottle of wine! Definitely a wonderful stay, and we would definitely look her up next time we are in town.
