Mark is a very nice host. He responds fast and makes sure you have everything you need. I stayed for a month in his studio. It's a very nice room with everything you need. Exactly as advertised.
Although there is a cleaner which cleans the toilets and showers, both seem old and have a somewhat gross feel to them.
The shared kitchen is very nice and has everything you need. One of the neighbouring rooms seemed to host a somewhat manic person during my stay, often loudly laughing or cheering at night, so you might want to bring earplugs!
