Flat has a great view over the Paris rooftops and it sets you in a really romantic mood with an Eiffel in front of you at all times. Place is nice and cosy, a bit old-fashioned but it has certain charm.
We were unlucky to come during a very hot weekend in Paris, it was over 30 C every day, and this flat being right under roof heated like an oven during day time. Nights were pretty difficult as well, as we had to close metal blinds to block sunlight in the morning that obstructed ventilation.
If it wasn't up to the weather or stay would be perfect. Montmartre is a stone throw away and underground station is right in front of the house. There is also a big grocery store in the opposite side of the street. Neighborhood is nice and very historical. The only thing to keep in mind (tbh I am not very good in knowing Paris neighbourhoods) is that the area between million rouge and Pigale and around is packed with strip clubs, private dancing, saunas and sex shops. It is not really noticeable during the day, but at night I all felt a bit dodgy to me and I wouldn't risk going outside without my husband. I might be overreacting. All together we had a great stay and Patrick is a super welcoming host who was always available and answered all our questions and accommodated our extended travel suite with early arrival and late departure.
