Fred's place is absolutely fantastic. It is situated in a quaint part of town where you have access to everything without a lot of the noise. Perfect for two and could see it accomoding one or two more.
The check-in was easy and predictable, even when the RER made us take a bus and delayed us an hour. The Paris helpline was amazing.
The kitchen and dining room were user friendly, we found a small grocery nearby. But the real gem was the Rue de Martyrs market. Best bread, cheese, and Macaroons of the entire trip. Breakfasts were all made in the flat, along with several dinners.
The bed was comfortable but watch the steep stairs up to the bedroom. Nothing we couldn't handle and all part of the charm as the room also included amazing skylights that made waking up to the street noise in the morning something to look forward to. We slept great each night, even the warm nights when we had to use the air conditioner.
The restroom and bath/shower were comfy and we never ran out of hot water. Don't expect lots of elbow room but everything was modern, clean, and fully functional.
We never turned on the tv, likely a good sign. But the wifi was easy to log onto and was much faster than our phones.
The building was secure, two layers of locks to gain building access and then a couple of intimidating locks on the front door. Always felt safe in the neighborhood, even with late night entries.
Fred was a delight and checked in multiple times. He gave advice, has lots of books around the apartment for tourism advice. And I loved his taste in music!
Stay here if you can, we will definitely be back to this incredible Montmartre flat!
