The loft was quite clean, however it is located on the top floor of the building, which is the 4th floor. Narrow staircase winding to the top can make bringing large bags up the loft very challenging. There is not elevator/lift to get to the top, so you are on your own bringing your bags to the top.
The loft itself is also multi-level. The beds are located on the second floor, also more stairs, which are quite steep. There is also many points where the ceilings are quite low, so be cautious for those who are tall. I'm under 5 feet so I had no problem in the entire loft, but my husband is over 6 feet tall had to bend and duck a lot throughout our stay.
The bathroom and the kitchen are located on the first floor of the loft. Both were clean and had all the amenities you may need. There is a hot water heater in the bathroom so we didn't have any issues with hot water, perhaps with a group of 4 you might run out of hot water if people take long showers. The AC was located on the second story of the loft so the first story would get pretty warm at times.
There is only one set of keys so if you plan on doing separate things this could be challenging, as the keys are required to unlock the door from the inside and the outside. You can utilize the lock box to store the keys unless one of you is using the garage located off-site where the remote is required. There is some logistical planning necessary then.
The loft is located near the train station which is nice if you are coming from the Lyon Airport, you can take the express train to downtown Lyon and walk to the flat. There is also a grocery store located outside the flat as well. Which was necessary for us, as we ran out of essentials at the flat.
There are two beds, but for us only one of the beds were made with bed sheets. I would recommend messaging the host a head of time if you plan on sleeping separately to assure that both beds are made up.
Overall, good location and the host was very responsive and on top of everything. You will get a leg workout for sure staying here! Enjoy the beautiful city of Lyon!
