We love the place! It's just a minute to the metro. When you look out the window you see one of the most impresssive churches in Paris. It's cosy and quiet area around the church, but just round the corner you'll find markets, bars, the rue Montmartre, and all the sights close to the Seine.
Nicolas is very friendly and supplied us with tips during the stay.
The flat is absolutely as described, the bed is surprisingly comfortable. There's nothing we had missed.
