We've stayed there last week and it was great! The palce is very quiet and the building looks very respectable. Flat is big, sunny and very elegant, you'll find everything you need.
Metro station is very close, Monoprix and Franprix supermarkets are in 5 and 3 minutes walk. Main sightseeings are also close to the place.
Soline is amazing, very friendly and helpful. We enjoyed our staying there!
