My sister and me stayed in Yves' place for a long weekend and it was absolutely wonderful! The neigbourhood exceeded our expectations; away from the masses of tourists, but with many great places to eat and shops around, and very close to the Marais. Plus probably the best patisserie/boulangerie in Paris around the corner!
Checking in was easy and descriptions were very clear. The building is beautiful and well maintained. The apartment is small, as are all appartments in Paris, but very cleverly designed. All you need is there - kitchen, shower, washing machine, dishwasher, cabinets. The sofabed was very comfortable and the view over the market square and the city is unbeatable. The blinds made sure we slept comfortably without the morning light waking us too early.
All in all we had a truly lovely stay in Yves' great and clean appartment, in a wonderful neighbourhood. Would surely stay here again!
