Maria's place is great! Location is really great - so close to the U-bahn and also to the Hauptbahnhof for when you arrive. The neighbourhood seems very nice and quiet and the local bars/cafes and eateries all great for a variety of budgets. It's a super clean and easy to maintain apartment - very simple and has everything you need for a 'basic' stay. I felt very comfortable and at ease there. The double bed was very comfortable indeed and the single one in the 'den' area looks like it would be fine to sleep there too. Communication was fab, Maria was very helpful when I needed to get in touch with her and very light touch. Check-in and out were very easy too - especially since I was arriving so late. It also feels private in that block/apartment. The building/block hallway is magnificent! I recommend staying here, I stayed for 4 nights and really enjoyed it.
