I spent 2 weeks at Tom's apartment.
Since there are heaps of good information for general travellers, i'll tell you why it's also good for family travelling with kids.
-perfect room heating
-hot and strong shower
-washing machine, dryer, dishwasher and full kitchen
-good location to kids' tour spots
-easy access with pram through 2nd floor entrance
(although there was the last part of the renovation going on exactly during our stay, it was not what Tom could expect nor we had much problem either.)
good value for the price
i ll definately recommend and stay here again.
