This reservation was a huge disappointment. I was initially instructed to pick up the key at the workplace of one of the hosts, which was a 25 min walk from the AirBnB. I obviously asked for a more convenient pick-up place for the key and we agreed on a nearby bar in St Gilles. But what was more troublesome is that the hosts had not provided us with the correct address, the one advertised on AirBnB clearly not being the right one. My spouse and I together with our 19-month old baby waited for nearly 90 mins in what we later found out was not even the correct house, all the time thinking we had been given a wrong key. It was raining and it was cold. (Luckily a kind neighbor had let us in her house so at least we had shelter.) During whole this time none of the two hosts could be reached by phone. Given the advanced hour — it was almost 9:30 pm by then — and as our little one was extremely tired and had to sleep, we were forced to book a very expensive last-minute hotel in the vicinity, plus pay for an Uber to bring us there. When one of the renters finally contacted us at 10:32 pm, we were already in the hotel. We have never had such a bad AirBnB experience.
I must add, to the credit of Stéphane, that once he had found out about our situation, he showed much sympathy and made sure to immediately reimburse us.
