A lovely place to stay for a week. Homey, and it was comfortable for both work and relaxation. The location is great, and close to a couple key metro stops. Oh, and make sure you know each of the three ways to access the city from the apartment---to Rue Veron (for Abbesses access), to Clichy for the main drag, and Robert Planquette. Knowing these access points will make it feel like you can walk out into three totally different areas---very cool!
Oh, and it's a little walk, but go to Signature for dinner---it's freaking amazing and the guy who runs it is unreasonably friendly and helpful.
