My stay was perfect in every way. The apartment is super cozy and the decoration is really cute. Everything was very clean and tidy and the room was incredibly comfortable. It's also relatively central, so you could easily walk to most places, but the the tram and bus stations were also a short distance on foot and had direct connections to Flagey, Saint-Gilles, orJourdan. Of course, pharmacies, supermarkets restaurants etc. were all close by and you wouldn't have to walk too far to find a nice place to eat or drink.
Justine was also an amazing host, from offering assistance during a medical emergency, to overall being a nice person to be around and speak to. I can only wholeheartedly recommend her to everyone.
