In a nutshell: fantastic location, great wifi, responsive host, clean, and safe neighborhood.
I really enjoyed staying at Tristan's. It's close to everything and the windows do a great job in insulating the sounds from the restaurant down the street and there are solid blackout curtains. I had no problem getting to sleep.
There is a great laundromat around the corner that is easy for non-French speakers and the equipment works great.
The unit is on the ground floor and I often had the window open. With the curtains extended and the window open, you have both fresh air and privacy. The wifi was fast and I didn't have any problems streaming videos or doing video calls for work.
If you need a change of scenery while working, there's a great coworking space less than 10 minutes away (Anticafe). This place is perfect for minimalist digital nomads or tourists visiting Lyon. Thanks, Tristan, fir a fantastic stay!
