I recommend Maria's flat completely. It is in a great location - 10 minutes on foot to all the famous sites. It is clean and comfortable, the rooms are enormous and very stylishly furnished. It is opposite a former bunker now a famous modern art gallery but you have to book a lot of time in advance to see it. There are lots of cafes and restaurants around. It is though very quiet.Check in and check out was smooth and easy. Maria let us leave our luggage until 12.30. I would definitely stay in it again next time.
