We had a great at Bruno's place. Check in was easy and he was there to welcome us. Location is excellent. Close to metro, bus, and walking distance to restaurants, bars, bakeries, etc. Dry cleaning and laundromat nearby. Supermarket for all necessities across the street.
The loft bed could be a challenge for some guests and we hit our head a couple times so be aware of this. Also you need to be careful when going up and down because there is no railing on the steps. But that is evident in the pictures he shows. Also be aware that there is no outlet (or lights) next to the bed for charging phones or other needs.
The toilet and the shower are physically separated. The shower is narrow but that seems to be common in Paris.
The apartment is very quiet and we never had any outside noise.
You don't really need the A/C but we turned it on for a few minutes a couple times and it was nice to have (portable unit type)
We enjoyed our stay. We loved the neighborhood and Bruno's place was well appointed, clean, well decorated, and very convenient. He is a very responsive host.
