Ups: sparkling clean, the host is always in touch and super nice, WiFi is fast, location is hard to beat - you are right by Louvre, Nespresso coffee machine came really handy, a bottle of wine was waiting for us upon arrival. The place is made with love and decorated with taste.
Downs: it is super tiny, low ceilings, no air conditioner, so if you arrive in the summer you will suffer from stuffed air. If you open windows - you won’t be able to sleep, because it is super loud. The bathroom is microscopic, too. It reminded me of lavatories on the plane in terms of size. So, if you don’t care about apartment size and heat - rent it! You will be very happy with the location and cleanliness.
