Helie's place is indeed a small pearl! We had five great days. It is located very central in Paris, within walking distance of Gare du Nord and only 200 metres from closest metro station. Nice tiny restaurants around the corner with friendly people. The place itself is quiet, no street noise heard in the rooms, as the appartment is not located at the street itself. Appartment is clean and recently refurbished. Nice living room with good quality sofa and chairs and very useful kitchen. Electrical heating system works very well. Bedroom bigger than expected with very good quality bed. Nice shower. Helie and Laeti gave us some very useful tips where to eat, where to go for running, etc. In short, we certainly recommend you to stay at their lovely place.
