We stayed here as a family of four for several nights, and this space worked well for us and was also convenient in terms of the location.
The listing is accurate and the photos give a good idea of the space and the number of beds. Everything in the flat was clean. The heating and hot water were both working well, which is important in December. There is a four-burner stove and enough dishes, pots, and pans for meals.
The windows are huge and let in a lot of light, so if you are staying in the summer months, I would recommend an eye mask. I did use earplugs, but I would say that probably wouldn't be necessary for most people, as this location is not on a​ busy street.
The location was perfect in terms of access to public transport.
