I don't think we'd stay anywhere else when we return to Paris. Glenn's apartment is so beautifully decorated and a good size by Paris standards. He has made great use of the every single inch of the space. He was waiting for us on arrival, took time to explain everything including Metro locations, boulangerie, pharmacy, and other local spots. The bed was a king and very comfortable; the bathroom was spacious with a great shower. (Note: the tub could be tough to get in and out of for older folks, but we managed just fine). He has thought of everything and is a five-star host.
The galley kitchen is tiny. We only prepared breakfast there as we were out enjoying the city the rest of the days/evenings. However, it is well equipped and one could cook there easily. We were especially appreciative of the Nespresso machine for our morning espresso.
I can't think of anything negative to say, we had a wonderful 5 days and would return in an instant. Highly recommended.
