Great place, well located for public transport and for walking to markets and shops but the 13 arrondissement is not a tourist area so there are no crowds and the bistro prices are not inflated - eg La Menagerie. Jean's place is quiet - a great place for a longer stay because it has a good set of kitchenware, stove, microwave and the kitchen is separate. Also a washing machine that spins well and the clothes dried quickly on the drying rack. It also has a bath!
A minor downside is the entrance (mind your head).
Well insulated and heated for colder weather (we had snow in April!).
