The flat on Rue Claude Tiller was just okay, there were a few challenges.
There wasn’t working air conditioning when we stayed, only an oscillating fan that didn’t fully work, and it created an uncomfortable night. In addition, the shower in the back bedroom had issues with a very slow drain, causing water to pool up in the shower pan. Even taking fast showers, you would worry about it spilling outside of the shower. I reported both issues to the Reservation Desk online, and I received a “let me check with my colleague and get back with you soon” response, but no action.
The location is good. It felt like it was off the beaten path, but close to transportation: the Metro at Reuilly-Diderot station is probably less than 100m down the street, the Nation Metro station is about 750m; the Gare de Lyon train station is an easy walk at just over 1km. There were plenty of restaurants close by, attractions are about 2-4km away.
