The room is just like in the description: private bathroom, equipped with microwave and mini-fridge; comfortable bed; it is also very quite and, though outside may be cold, the temperature inside is just perfect.
It is at walking distance from EPFL (15-20 minutes). Bus stop is at 5 minutes walking.
The host is very helpful and available and strives to make you feel as comfortable as possible.
I highly recommend this host.
