4 Rue Chambiges is a particularly fine place to make an extended stay in Paris.
It is easily one of the best locations in Paris. I have often stayed at Plaza Athénée, which is located immediately to the south, one block away on Avenue Montaigne, so this wasn’t a surprise with respect to shopping, dining and the sights and attractions, but staying for a month brings other needs and all of them - BNP ATM, Monoprix, Pharmacy, Sephora, wine stores, fromagerie, dry cleaners, etc. - are just 5-10 minutes away. And fresh markets not much further away.
The apartment is bright from large windows in the spacious dining/kitchen room and the living room which are both perfect for entertaining, relaxing and working on the computer. The apartment , situated on the 4rd floor (Floor #3 + 0 Floor), was quiet and comfortable in all respects.
