PROS: Excellent location in the heart of Le Marais with many cafés, cultural spaces, and historic sites in walking distance. Our host was very responsive to our inquiries. The apartment was clean with basics provided (although the coffee maker did not work) and enough room for 3 people.
CONS: Despite inquiring in advance about an elevator/lift in the building (as two of the people in our party had trouble navigating stairs due to age and disability issues), and being informed that there was one onsite, when we arrived, the "lift" was in the very beginning stages of being built and we were forced to navigate an active construction site with few if any safety precautions, such as a railing on the already narrow and rickety staircase, every time we entered or left the apartment.
Also, the "contactless" check-in process involved using a code to pick up the keys from a store several blocks away, but the code we were given in advance did not work. Because we had just arrived from the US and had no phone service, we had to borrow the phone of the store proprietor and leave a message with yet another party and wait for the host to call us back with a new code. After a full day of overseas traveling we found this process flawed and stressful.
