Location is magic and really the best value in Paris.
Apartment was clean and neat. Just 250meters away is a Carrefour supermarket plus Metro and great boutiques. It is also very easy to walk down Rue Des Martyrs and reach many major sites by foot such as Galleries La Fayette, Opera and a little further on is Concorde and the Eiffel Tower.
The streets behind the apartment are also gorgeous to walk along to Sacre Coeur.
The street of Yvonne Le Tac is quiet, however there is a little noise in the apartment with it being on the ground floor. However for us Ground floor access with the kids was perfect.
Suzie also had a cot and high chair ready for us, which was excellent.
