The best:
Location, in the very center of Paris, near metro and all comodities that you will need.
The host: helpfull, kind and fulfilled all our requests. The price considering the location and the maximum number of guests.
The worst:
Old house, worst that appear in the photos, need some urgent fixings;
Old builing with narrow stairs (the appartment is in the 4th floor, no lift);
The cleaness of the appartment could be really better
The appartment is for 6 guests but have only 3 chairs for meals and a small table;
The noise at the street, all night, specially at the weekend
