Sevim is a really friendly and welcoming host and her communication was great, she made me feel very at home in her flat, offered beer and nice conversations on her roof terrace. The flat was also spotlessly clean.
I would say that if you are planning to book this room you need to bear in mind there are no curtains (though Sevim did warn me to bring an eye mask after I had booked), and it is quite noisy from trams/traffic/construction work outside the windows. The room is also not private, as Sevim and Mike use the fridge in the kitchen. Overall it is a good budget option, simple futon in a living room, but be aware of the noise and light if you are a light sleeper.
