Let's start from negative (there will positive as well, promise) - pictures don't correspond to the reality. Appartment is definitely much smaller, bathroom and kitchen are not renovated - I would suggest you to ask for pictures privately, so that you could decide whether to stay in this appartment or not.
POSITIVE - Amazing location and amazing view, building is very old and seems to be even historical (like in 'The Shining' with Jack Nicholson). Also the host was very communicative and helpful, quickly responded to our request.
Overall, we had a good stay because appartment was not our goal, our goal was to see Paris. BUT we definitely overpaid & mostly paid for the location & the view - it all depends on your reasons why you come to Paris! :)
Hope this review was helpful and I wish you a good stay in this city!
