Bed is hard as a rock. Actually a futon with a thin mattress, not a bed as advertised. Back ached every morning. Worst bed in any of the very many AirB&Bs we've stayed at.
Check in was a nightmare. Told a few days before arrival to pick up the key at a different address (nothing in the advertisement about having to do that). Given the idea that it was just around the corner at a cafe. Turns out the cafe is half a kilometre away (seriously). The proprietor couldn't find the key and tried to phone the host but her phone was switched off. With a lot of trouble and detective work we found the key. Then had to walk half a kilometre back. Thank god it wasn't raining and I could leave the suitcases with my traveling companion outside the AirB&B place. It would have been an ultra-horrible experience for a person travelling alone. Grossly overpriced, even for Paris.
