We've just spent two nights at Catherine's place and loved it. It's a beautiful flat located on the first floor, with views onto a peaceful courtyard. We appreciated the tips for local restaurants and the clear arrival instructions, and was great being so close to a couple of brilliant boulangeries, nice restaurants on rue Lepic and Metro stations too. I'd really recommend staying here if you'd like a cosy quiet homely space in the middle of Montmartre.
