Location-wise it was perfect for our short (3-4 days) stay. Its central location in Old Lyon made all the places we wanted to check out readily accessible. The building was also centuries old (I forget exactly how old but much older than you'd think) and very much part of the fabric of Old Lyon, and its authenticity made our stay feel extra special.
Nicolas was very prompt with communication and his/Coralie's recommendations for bouchons and bakeries were on point (The bouchon was a blast!) The room is minimal and efficiently equipped as advertised, and the toilet is actually on the very right as you walk in, separate from the shower/sink on the other side which was nice. We did have to crank up the radiator pretty high at night or else it got pretty cold, but this seems pretty much the norm during winters in France.
There were some unexpected aspects, however, that we found lacking that affected our stay:
1. Hot water was unreliable at times- maybe 7-8 minutes into my shower the hot water suddenly turned cold, and I was stuck trying to get all the soap off my body and shampoo out of my long hair with ice-cold water, in the middle of winter no less (Nicolas did promptly respond and guide us to reset the boiler settings from auto to manual - but warned that it'll take at least 30 minutes to start kicking in.. and I couldn't wait around that long in my half-clean state.) It wasn't as if we were being indulgent with the hot water either (my husband's shower before me lasted less than 5 minutes.) I hope this gets fixed so nobody else would get stuck in the same situation. 2. There was some intense! renovation going on in the same building- one day the dust was so thick and filled the entire inner courtyard that we had to hold our breath and squint our eyes just to pass through the hallway. The deafening noise lasted all morning which made it hard for us to enjoy the breakfast we picked up from the bakery. Nicolas seemed pretty surprised as well with how bad it was.. we may have been particularly unlucky with our dates. In any case we ended up just heading over to where our friends were staying to avoid any goings-on. 3. The TV is pretty ancient.. and complicated to use. In the end we concluded it was just easier for everyone to just not touch it at all.
Despite all this, we still felt well cared for and since we were out most of the time the above factors weren't that much of a nuisance. Esp. given its superb location, we'd probably consider staying there if we were to visit again.
