Lovely quirky house and convenient for metro. Make sure if you are using the Metro when arriving you get off at Montreuil station. We didn't and had difficulty finding the house.
We loved the house and our young granddaughters thought it was great. The metal spiral staircase was a bit of a challenge with a few heavy suitcases and older legs!
Our only suggestions would be the addition of a second bathroom/shower and a washing machine would be useful. We ate out, other than for breakfast, so didn't use the dishwasher.
A great place to stay for getting around the sights.
