Alex as a host is the best. Clear, timely communication and always accessible. The apartment is in a perfect location in the heard of Paris. Beds are large and comfortable, linens and towels of good quality, and everything works well. Not air conditioned, but the usual Paris large windows suffice. Plenty of hot water and deep bathtub as well as shower.
Toilet room and shower are at opposite ends of the apartment, making for lots of movement around the apartment as needs arise. This can create a disturbance for sleepers as the floors are very, very old and very, very noisy. If you are sound sleepers and have a white noise machine, may be ok. Otherwise you may will have an issue.
I told Alex we would happily return after some floor work, but not before. As a side note, paver stones in the courtyard are being removed and replaced. Jack hammer is involved. It's going to take a while.
Honestly, I wanted to write a perfect review as Alex is such a delightful guy and a super host, but I wrote as objectively as I can.
