My husband and I spent a fabulous month at Guillaume's Paris apartment and would book it again in a heartbeat.
Barbara was waiting for us on the sidewalk to let us in the apartment and helped us with our large amount of luggage (there is an elevator). The place was very clean but Barbara pointed out the washer/dryer was still running, drying some towels. Turned out it was absolutely packed full of towels and it took us rerunning the dry cycle to get everything sufficiently dried to put away. There was also some paperwork, in French, which included an inventory list (in French), that needed to be signed.
The appliances were of high quality and all worked perfectly. The water pressure was good and we never had any hot water issues. The lighting (both interior and ambient from outside) is excellent. The physical space is plenty ample for two people and visually appealing. We found the bed to be very comfortable and there was plenty of storage and closet space. The apartment was well stocked to get by a few days before needing items like paper towels, etc. The Internet was extremely reliable and fast. The TV was large and programming included a few English speaking news channels. We did not use the printer, the Bose speakers, the radiators, or what I think was the air conditioning. I thought we would have free international phone service through the landline for calls to the US but that was not the case. There were lots of books on seeing the area (some in English and very good) plus books for pleasure reading.
The complex is very secure with two exterior locked doors, is in a fabulous location, and is very clean. The only cautionary note on the complex is that sound really carries (especially if the windows are open). The neighborhood has everything you might need with grocery stores a few blocks away and a small market right across the street for those evening ice cream or fruit for breakfast runs. Boulangeries abound for your “take-away” sandwich for your next outing or to splurge on some evening pastries. Multiple metro stops a short walk away made getting anywhere quick and easy.
Though we did not get to meet him, Guillaume was always very quick to respond to all communications. Check-out was accommodated for the night before we flew out, as our car was scheduled extremely early. Mike spoke English very fluently and the check-out was quick and smooth.
