We had serious issues BUT I want to say that I liked this apartment very much. Great location (a short walk to the Tuileries and the Louvre), beautiful flow of the apartment from its dining room into the livingroom, the large windows looking out on two directions, the charm of its furnishings. My partner, our dog and I were there for 35 days. (Great baguettes and other treats at Yannick Martin bakery a short distance away on Rue St. Honore. ) Tomas was a great host, easy to reach, very responsive to our issues and concerns.
That said, I think this apartment wasn't ready for rental at the time we took it. A new hot water system for the shower had been recently installed, and the electric lines in the unit couldn't handle it. Electrician came numerous times during our stay to repair. (Shower when working was adequate, but not great water pressure.)
Wifi was very slow. 10mbps on a good day. I know Tomas will be working to upgrade this.
Also, a construction project on a new business immediately below us made daytime life hell for the last 10 business days of our time there.
So, in short, all of our complaints/problems will almost certainly be fixed or completed by the time of a next stay; and we would consider staying there again. There's a lot of traffic on the main street outside but it's pretty quiet at night. The kitchen doesn't have a standard oven, but there is a toaster oven, disher, microwave, 2 gas burners, tons of plates and glasses and silverware. There's a washing machine, no dryer but a drying rack. The apartment was easy to access. You will hear the upstairs neighbors walking around above you. It's an old building, comfortable furniture, lovely furnishings, a good price (if all things are working). We did get a small refund to compensate for some of our troubles.
