Marc's place is easy to find - 10 minutes walk from Wiedikon station. Getting the key from the lockbox was pretty easy too. There's a lift in the building (although there's a substantial step into the building, so not really good for disabled access)
The flat itself is clean, light, airy and spacious, with one big bedroom, extra guests can sleep on the sofa in the lounge (extends to a double) or the sofa in the hallway (also extends) There's a good-sized television and wifi internet access - although we found the wifi doesn't easily stretch across the whole flat - it's best to be in the bedroom or hall.
The location is a little bit noisy; but the excellent blinds/shutters hold out the noise very well indeed.
A few minor problems... the coffee-machine didn't work and leaked water when we tried to use it, but the kettel works just fine. Also the dishwasher didn't work at all - it looks as though it has no power and hasn't been used for some time.
It wouldv'e been nice to find a few provisions (tea, coffee, sugar, salt, pepper maybe?) but the local co-op is only 3-4 minutes walk away.
