Martha's place was clean and as described. The amount of "rules" and tone of them was a little off putting but Martha actually seemed very friendly and thoughtful. The place is up a very steep hill so bear that in mind when looking at walking times from restaurants etc.
The fridge, kettle and microwave are upstairs but the sink is downstairs so expect lots of going up and down.
The only plates, utensils and cups provided are disposable which makes doing anything more than heating simple food up impossible.
