We had a great time staying at Maison Claude.
The apartment is well located, with restaurants and bars very close, and tourists spots either a walk or short tram ride away! It's a well-decorated, homey space that has all the basics you'd need.
The apartment is a little on the cold side in winter, with draughts sneaking under doors and chills through the old windows. Not a deal-breaker, just be ready for that. The heating is a fixed temperature (though perhaps could be discussed with host).
The place is facing the main road and this does result in a lot of noise being carried into the apartment. If you are a light sleeper, maybe something to be aware of. If you like feeling like you're in a bustling city though, you might like it.
All-in-all, would recommend. Very good communication with the host so you'll feel looked after at all times.
