We were staying here for 4 nights, everything was clean and very-well equipped: paper and bathroom towels, soap, a fan we've found very useful due to 35°C outside.
TV could also come handy, since it has chromecast onboard.
In the kitchen we've had all we needed during the stay: a pan, several pots and everything else for typical cooking - oil, salt and pepper (even some seasonings).
There were even some tea and snacks.
You can wash and dry your clothes in the basement - there was no even need in any supplies.
Thin walls here do not protect you from hearing the furniture being moved by neighbours or sometimes flushing in the toilet, but it was totally fine in general.
The location is very nice: cozy neighbourhood, ~5 min from Pétillon station.
We were happy to stay here, and had everything we needed (and even more). Ksenia is a very friendly host, quickly responding and polite :)
Totally recommend as a place to stay
