I came to Paris for a work trip that required wifi for file syncing, uploading, communication, and meetings in the evening. Unfortunately, the apartment's wifi was not working the entire time I was there due to an overheating router. Yves's team communicated with me diligently about attempts to resolve it each day, but this one problem greatly affected my trip. Yves kindly gave me a partial reimbursement to cover the international roaming and eventual portable hotspot that I had to rent. If you absolutely need wifi, I would recommend verifying the router is now in working order.
The apartment itself was quite lovely. It was very thoughtfully and strategically equipped. The kitchen was well stocked with equipment and utensils for cooking. It even had a dishwasher. The shower room and the toilet room were the nicest and most well ventilated of all the small Parisian apartments I've ever stayed it. They were clean and up to date. The balcony has a nice stool to sit on for one person to enjoy the views and a cup of coffee. The one weird thing was that the cleaning company had appeared to spot clean things, so the shower, sinks, and toilet were immaculate but there was dust on the rungs of the towel warmer that I had attempted to dry my clean clothes on and there was some moldy bread, opened drinks, and dusty drawers in the kitchen.
To sum up: This is great place to stay if the wifi is working. I appreciate how responsive the house management team was.
