When I arrived Faes and his girlfriend were very welcoming and excited to have me. Their positive and bright attitude towards guest is something very welcoming. They were very gracious and would teach me about where to visit in Geneva (also made sure I don't get lost and remember where to go :D).
The apartment is nicely located near the center of the city AND the lake which means you can get to both of them very easily. In fact if you want a walk after a nice Fondue dinner at home made by Faes, you can take a walk to the lake which takes 6 - 8 minutes by walk.
Also, Faes has recently introduced a special Fondue dinner (15 Franc per person) if you are interested in Swiss fondue but are afraid of the high prices in the restaurants. I highly recommend trying it and be sure to have it warm tea.
10/10 would recommend this apartment because it is conveniently located in the city and near the lake and Faes and his girlfriend is just a pleasant company to be with if you are on a long trip.
