The place is good, would recommend. We really felt relaxed and comfortable.
Maybe not for longer stays, but please see detailed description bellow.
Pros:
The location is great, 5 minutes to a metro/buss and 15 mins to a train. And it's really close to some popular areas. There are markets and restaurants (even vegan options) all around.
The bed is really comfortable - really! We slept like babies. And the furniture in general is comfortable and nice looking.
There are various appliances that you could find useful - washer, iron (and a board), vacuum cleaner, hair dryer etc.
Everything seemed quite clean and nicely arranged.
There's a lot of light and a good draft can be made, the windows are good.
For the hosts, Derya was really great and responsive during our stay (helped us and informed us), and David welcomed us really nicely.
Bearable:
There is no wardrobe closet, only three drawers and a rack with hangers. This is the only reason why I would not recommend a longer stay. For us, for seven nights, it was functional and we really didn't mind (the clothes was everywhere :) ).
We had a short cockroach problem, but Derya responded in half an hour (seriously) and resolved it for us for the rest of our stay.
The hood is somewhat loud, but we didn't mind it (we slept well). You can hear dish washing nearby, but it stops around midnight.
Cons:
The shower. Generally the bathroom pressure and water control are bad, but the shower was really difficult. It's almost impossible to set the right temperature, and it varies by itself - mostly too hot or too cold.
