We had a wonderfull stay in Domitilles apartment! It's located directly in the centre of Montamtre with endless number of restaurants, tiny nice shops etc. Sacré-Cœur is less than 10 min away to walk. Paris Métro just 5 min.
The apartment itself is very well equipped with tasteful and stylish furnishing and provides everything you might require. Its small but used extremely efficient and very cosy. We can definitely recommend and will return if we'll manage.
