Overall: Disappointing. My wife and I stayed in Sidney's flat for two weeks while we eloped in Paris. Nothing was terrible - no horror stories - but we were disappointed with our stay, the listing, and the follow through. Here is the pro/con list:

Pro:
- Sidney's partner Max was wonderful. He helped carry our bags up to the sixth floor when we first arrived. He sent a number of text messages throughout our stay and did his best to address our concerns.
- The location is fantastic. Plenty of cafes, shops, and sites within walking distance. Very safe, very fun.
- Lots of natural light.
- Comfortable bed.

Con:
Since we were living here for two weeks, we needed four things - a washer, AC, wifi, and a kitchen.
- The washer doesn't work. We were told that the washer didn't work after we checked in via text message.
- There is no AC. When we asked about it, we were told it was an old building and there is not any. Max did try and find a portable unit 10 days into our stay but was unsuccessful.
- The wifi is spotty. It wasn't unbearable but it would go out for hours at a time.
- The hotplates are broken. Portable hotplates were provided but the unit took up the only counter space available as it is a small kitchen.
- We never met or communicated with Sidney. Max was fantastic but we found it strange to never communicate with the listed host.
- Some essentials were missing. The towels, sheets, and toilet paper were abundant but all of the soap containers (shower, hand, dish) were empty. Cleaning supplies were also empty (paper towels, general cleaning solvent).

Overall, we were disappointed. The flat is not as advertised and would have never come up in our search had the description been accurate. For the price, we could have stayed in a place with all of the items we needed for a good trip. We made do, and if you don't need a washer, AC, wifi, kitchen, and/or essentials, then this place is great. But if you do need those items, I strongly advise you communicate with Sidney or Max with your precise needs, even if they are listed, before paying.
