Stayed at Apart Hotel Sagitta during February 2022.
Pros: The location is perfect for exploring Geneva. The staff are friendly and speak English. The room is large, clean and quiet. The double bed is very large and very comfortable. The TV has a number of channels from different countries including the UK. The rooms are serviced but you must put a "please clean my room" sign on the door handle otherwise the room will not be cleaned.
Cons: The kitchenette is tiny and has no kettle so water has to be boiled in a saucepan. Will be very difficult to cook anything but the simplest meals. There is a fridge so we limited ourselves to making tea and coffee and having cereal for breakfast (note that airbnb guests do not get breakfast provided by the hotel). The room was overly hot and turning down the thermostat didn't seem to do anything.
Overall, we would recommend this hotel for a single person or a couple
