Pros
Wonderful location surrounded by various Metro stations, restaurants, fast food etc.
Jonathan was always responsive
Apartment was nicely decorated if a tad spartan
Cons
Some may not know however Rue de Ponthieu also has 2-3 bars which convert into nightclubs that ended up with people shouting, cars stopping to chat with club-goers which thus led to the cars behind (it's a one way street, mind) hitting their horns repeatededly from about 4am until 7am. This happened to us on Saturday, Sunday and Wednesday early morning - it may be an isolated occurence but travelers be warned as it led to poor sleep, kids being woken etc. The street itself was a mess as a result with used balloons, cream canisters, urine and empty beer bottles strewn out the front of the apartment and all along the Rue. A real shame but this point needs to be highlighted, sorry Jonathan.
The car park is ok if you drive a small car but anything large ie. Range Rover will be a logistical nightmare to navigate the tight turns down to underground level 5. Mind the low ceiling too when opening the 4WD boot door as in our tired state, we opened it without thinking and there is now a dent in the middle of the door.
