I went to Paris to celebrate my birthday with my boyfriend, and we stayed 4 days in Leo and Violette's studio; where we really enjoyed our stay. The location is superb, only 5-10 minutes to the Louvre or Notre Dame. We preferred to walk and I can't stress enough how central is the flat.
The studio is small but very nice and has all the amenities, a very comfy pull out sofa, a nice shower and small kitchen where to have lunch or breakfast.
I definitely will recommend this studio any couple that would like to travel to Paris.
