Are there microwave and mini fridge in all rooms?

If you get a room that does not have one, you can call the front desk and they will bring one to the room.

I think there are minifridges, but you have to ask for a microwave.

No

Not necessarily, but if you need one, call the front desk.

Yes

Depends on the room. Some do have a mini fridge. Some have both. You may want to request the room that you need with a microwave and mini-fridge.
