The flat is in a great and central location and very clean. Hot water and everything else works perfectly. The place has lots of windows, yet stays quite cool when it's warm outside. As others have mentioned, you should be prepared for the narrow stairs, but they are safe and not a problem if you travel with a backpack. Also, such stairs are quite common in older buildings. The kitchen has all necessities for two people, but if you want to cook a lot you might miss one or two things. I can recommend the place heartily, and since it is quite big it is also well suited for longterm stays!
