It's nice enough. The facility is clean, all the machines were functional, and it's an easy walk from the local hotels.
There are plenty of machines but I would still recommend getting there early to beat the crowd.
Good
The laundry's street address is located between 27 and 29, not 61 as shown on Google. A straight forward self-serve laundromat that charges 5 CHF for a small load, 10CHF for a large load of washing, and 1 CHF per 10 minutes of drying. You can buy powder detergent for 1 CHF per load. The coin machine does not take 5 CHF coins, so bring smaller coins.
Just an ordinary launder that is terribly hot.
This is possibly the only public laundromat in downtown Geneva. Prices as of April 2010 were 5 CHF for a load of laundry, then 1 CHF for each 9 minutes of drying. There were about ten washing machines, about seven dryers. All machines take 1 CHF coins - there is a change-making machine, but bring your own coins to be on the safe side. There is also a soap dispenser, I forget how much that costs. Like everything else in Geneva this is fairly expensive, but may be your only option if you need to do laundry and do not have access to a private laundry machine.
