Paul's studio is amazingly located right at the bottom of steps which lead directly to sacre cour. It is only a few steps to many great bars, restaurants and stores. It's location is really unbeatable. The metro was not running during our stay but its only 5 minutes away and the Monmatre area is great. It's about 15 minutes on foot to Gare du Nord.
The studio is really small but has everything you need when resting after exploring the great city of Paris. We had an issue with the bathroom plumbing but Paul was more than amazing in taking care of things for us. His English is very good and he always responded very quickly. 5 star host for sure. The bed is not bad for a sofa bed and I was able to sleep rather well, it was a little noisy outside on the weekend but we didn't mind and it never woke us up. We were also happy to see that the bathroom door has been replaced to provide a bit more privacy than what can be seen in the photos.
The TV is hooked up to a chromecast which was really handy during downtime in the studio. While we decided to take advantage of the diverse choice of restaurants in the area, you could easily cook here should you want to.
I would be sure to come again the next time I am in Paris. Thanks again for everything Paul!
