We've stayed at Gemma's Airbnb for a month and overall the experience has been great. The room is nice and has everything you need (including a portable aircon), comfy bed, a lot of storage, two huge bathrooms shared between all rooms, and a kitchen with all the basics you would need.
I did say that our experience has been "overall" positive because it can only be as good as the other guests. There are 4 rooms in total and at times it can get a bit busy / loud with people taking showers at 2:30am or making curries at 6:30am.
Also something that wasn't obvious to us when we booked is that there is no living room or other areas, so when at home you're pretty much stuck in your bedroom.
