I stayed Saturday-Wednesday in mid September. Some posts mentioned that check-in could be tricky after hours and I can see why, however, I paid close attention to the street names and building numbers and did not have a problem finding the key. Take your time and read the instructions carefully! I had zero problems getting into the building and finding the apartment.
The apartment is beautiful with high quality appliances like a miele washer/dryer combo (provide your own detergent) and a bosh stove & electric oven. There is a nespresso machine with a few extra coffees available to get you started as well as sugar, also an electric tea pot. The kitchen is fully stocked and I had all my meals in the apartment (Geneva is expensive!) As for the bathroom it is small and clean with plenty of towels and wash cloths. Shampoo and shower gel are provided. There is a blow dryer.
The location... it doesn’t get any better. The street is very quiet, next to a church. A few posts mentioned hearing the church bells but I closed the windows at night and turned on the AC unit/white noise (thank you for that!) and slept great. I heard no noise! You are located about 0.5 miles from Plainpalais square which has a farmer’s market Sunday & Tuesday’s. The market is full of delicious, inexpensive produce as well as other items for purchase. Another grocery store called Coop is 0.3 miles away is for everyday needs (closed Sunday). You are 1 mile from the train station and 0.8 miles from the Geneva Bus Station where tour buses like Flixbus will pick you up. Other various public transportation locations are about 0.3-0.5mile away - very close.
There is a serious deadbolt on this door so you will feel safe in this apartment!
Marc also leaves the number of a taxi company that will take you to the airport. The cost for two people with two suitcases for a 4:30am pickup was 38 Swiss francs
Would stay here again. Highly recommend.
