Philippe's place has a wonderful location for people who already know Paris well, and has seen the major sights. If not, it is pretty far from any major attractions and closet well connected metro line is at Bastille. But for the seasoned Paris traveler, it is situated in one of the most fascinating and wonderful areas with great places to eat, markets, nightlife, shopping and lots to do.
The studio itself is very small, and there is no natural light as it sits in a small courtyard with the only light coming from several floors above. I would not recommend it for two people - not even a couple, as the bed itself takes up the entire room when opened. The bathroom is very, very small and the access to the shower may be to narrow for a bigger sized person, the sink is behind the toilet etc and there is not enough room to get dressed. The kitchen is okay with most things you may need, including a fridge and washing machine. The bed itself is old, heavy and not the easiest thing to pull open.
