Beautiful apartment, accurate photos. The first day we would have gladly given it 5 stars. However after 7 nights we have uncovered the small pains of staying here.
There is wifi ONLY in the main room, the router (located by the front door) does not extend into the bedroom or rest of the house. In order to get email or surf, you have to sit out in the main room. The toilet doesn't flush right, a constant annoyance. Safe was locked and unusable. Power went out for 2 nights in both rooms until I located the breakers. They don't offer any English cable channels. It appears to be only a small monthly fee to add english speaking options for guests, and two tiny televisions to boot. The neighborhood is near museum Picasso, an extremely dull area - the few restaurants in nearby blocks are geared towards tourists (think: frozen fish at 50 euro for two) and there are only a few bars nearby. You will need to hike to Bastille for better offerings.
What the apt does offer is exceptionally nice; clawfoot tub, decent bedding, quaint atmosphere, plenty of dishes and extras. However it appears to be a service-run establishment, meaning it often falls short on the conveniences of actually staying longer than a night or two. We enjoyed our stay, very romantic - but would not stay again.
