Thanks Axel for hospitality and patience. We were travelling by car and lost some time in traffic jams so arrived 2 hours later than discussed, but he was waiting us at the apartment.
The flat has everything that you can need for short stay in Paris. Fast Internet, two sunny balconies and even parking!
Location is out of the city centre but public transport stops just at the corner so there is no problem to get in any part of the city.
Recommended.
