Pierre's place is very well situated with easy access to two metro stations and it was easy to get to and find from Gare du Nord. It's less than half an hour to the centre of the city and sites like the Eiffel Tower. The place is small, but cosy and well laid out. I was staying for work and so spent very little time at the flat, but it was a nice place to come back to in the evenings. It was very clean and easy to find everything. The five flights of stairs at least twice a day were good exercise too! It was nice to feel like I had my own space for the week, but communication with Pierre was easy. He and his daughter were great hosts! As a woman travelling alone, I also felt reasonably safe being out after dark (walking back from the metro etc.) in the neighbourhood and the building felt very safe.
