My boyfriend and I stayed in Lihong's apartment for a week, and the experience was fantastic. The apartment is well designed, comfortable, and cosy.
The location of the apartment is perfect, in our opinion it's the coolest place to stay in Paris. The bedroom is far from the street so there is no noise, and the living room is quite quite quiet as well. It is just 1 minute walk from the main streets and the metro. On one side there is the Pompidou and such and on the other the Saint Martin canal, both 15 minutes walk. The area is very stylish, with surprising gallery openings all over.
And to top it off, Lihong was very nice and helpful to us, always ready to help.
Highly recommended!
