The apartment is great as long as you know what to expect:
- It is small - but that's life in Paris.
- The kitchen is very small and it would be difficult to cook much more than simple meals here - but you're in Paris! Go out to eat or at least get take out!
- There is no AC - but again, most Parisians don't have AC. After even the hottest day (104 F) it cooled down nicely in the evening. You have to sleep with the windows open but the apartment faces a private courtyard so it isn't too noisy.
The neighborhood is great! Be sure to check out Rue des Martyrs on the way up to Sacre Coeur. The Thai place downstairs is great and there are a ton of great Asian and French restaurants near by. Rue Cadet also has nice spots for night cap after a long day.
