The location of the apartments is superb. Both Louvre and d'Orsay are in 5 min walking distance. Same time rue Bonaparte and the local area overall is not crowded at all (at least it was not during our stay in April). There is a number of good cafes and restaurants nearby as well.
We have found apartments to be surprisingly spacious for the city centre. That is largely due to its 3-floor structure. It is also nicely decorated and equipped with about anything you may need.
The apartments are hosted by the charming lady, Valerie. It is sad that she had to leave Paris during our stay. Otherwise we would gladly attend her atelier, that we plan to do during our next visit to Paris.
