Guillaume was very friendly & welcoming. His flat is in a brilliant location - we saw all the major sights without a need for public transport, and were just a 10 minute walk from Gare du Nord. Lots of mini-supermarkets and cafes/restaurants along nearby main road.
The flat itself was good, with private shower and well-equipped kitchen, but the standout feature was the terrace - perfect spot to relax with a drink or enjoy some food!
