Rémi's apartment is spectacular. First of all it's in a great location for a traveler. No, it's not In the Premier or the Marais, but it's in a lovely neighborhood in which one is immediately at home. The Line 1 Metro is just two minutes from the apartment. Line 1 takes you to the center of Paris in minutes. There is a gorgeous Saturday open air street market minutes walking from the apartment which has terrific food and all fresh from the farm. Also there is a comprehensive grocery store just around the corner for shopping all seven days.
The apartment itself is a very spacious with lots of light and very quiet. It has a balcony the full length of the living/dining space and windows galore. Windows are on both North and South of the apartment so there is good cross ventilation. The kitchen with windows is fully equipped so you can make great meals with all the food you bought at the Saturday market. It's in a modern secure elevator building, and everything about the environment is spotlessly clean.
The host/guest communication was extraordinary. The lady with the key to the apartment was waiting for us upon our arrival.
I've visited Paris several times, and Rémi's apartment is the best value for the money.
