Karl was a great host. Easy to communicate with pre-trip. Accurate answers and descriptions. Very accommodating to the schedule we had.
Since it was my wife's and mine first trip to Paris, we had our eyes wide open and wanted the place to match our expectations from Paris :) Karl's place was simply ideal for that!
100% match to pictures. Very vintage and natural feel of the apartment, you feel like le Parisien yourself :) Apartment, unlike hotel room, has all the little bits and pieces you might suddenly need and not want to go out to get it. Very convenient!
Location is perfect. Not too central, but close enough to everything, straight between Montmartre and the river. Also, not too many tourists around, which adds to the immersive experience :)
Karl was a good host during the visit - he never came around! :) But still willing to help though ( I have to add Karl does look like le parisien himself so another bonus point for extra feel ).
To sum it up, very happy with our selection, would recommend the place for a couple or max 3 people to stay in Paris. Would come back fo sho!
