Many positives: We would stay there again. Wonderful Location. Very responsive management. Immaculately clean. Modern and well-equipped bathrooms. Small modern kitchen. Lots of storage.
Could be better: Large beds were too long for the rooms. It made it difficult to get from one side of the bed to the other. There was about 14 to 18 inches between the wall and the end of the beds-- and there are wall-mounted TV's on those walls. I had to hold onto a mounted TV to navigate around the bed. (Not much fun in the dark in the middle of the night if you have to use the loo.) Having said that, the beds were the right size for the rental. The bedrooms were just slightly too short.
The sofa in the living room is more of a day bed. So deep you may need someone to help you out of your seat. It is perfect for a nap.
Very little artwork and mostly empty walls. ( I only mentioned this since the description reads "The walls are decorated with paintings, giving an artistic feeling.") If you take a look at the pictures displayed in the listing, you'll see what I mean.
The dining room table and coffee table are well-worn.
If you're thinking of using the loft/ 3rd sleeping area, you should be no more than 4 ft. tall. The sleeping area may be taller, but you have to be under 4ft. tall to get there. I never tried.
Neutral comment: My wife and our visitors described the flat as "masculine". Lots of dark wood built-ins, shelving and floors.
