We had a really great stay at Isabelles place in Montmartre! Isabelle and her husband welcomed us super friendly and gave best advices. The flat is beautiful and spacy - we stayed there with four adults and three children and there was enough space for everyone to retire. It even has a huge screen to watch movies which our children were excited about :) Besides the lovely apartment, the neighborhood at Montmartre is great - a lot of nice shops and cafés in rue des martyrs. We enjoyed our stay a lot and would love to come back!
