This apartment was very spacious and in a good location.
I think it would work alright if you only needed the two double beds. I was sleeping in the 'sofa bed'. What I didn't realise (because it's not pictured) was that this bed is actually located in a windowless room off one of the other bedrooms, with no door dividing them, which is a bit of an odd set-up - I had assumed it was the actual sofa. Worse, though, was that the 'sofa bed' was a single bed but half of it sloped downwards, so you had to stay on half of the bed only, which led to a very bad sleep. Needless to say the next night I moved to the actual sofa, but even as quite a short person I didn't fully fit on the sofa, so it wasn't a great few nights of sleep for me.
In addition, the flat is not nearly as cosy as it looks on the photos, and not well thought out for visitors. For example, the coffee pods provided didn't fit the coffee machine, and there were no basics such as milk, coffee or tea provided. A number of the lamps around the place didn't work - one of the bedside lamps wasn't plugged in and there was no socket within reach. In the whole flat there was one coat hanger despite lots of closet space. None of the windows opened so the ventilation didn't feel great, and the heating seemed to kick in only when it felt like it.
It had the potential to be a really lovely stay, but it's just not a particularly welcoming space, and a little thought about making guests feel comfortable would make it really great.
