The apartment is nice and well located. Kitchen is well equipped (no salt/sugar/oil though), dishwasher and oven work fine. The shower (temperature/pressure) is good and beds are comfortable. Kids enjoyed two-level planning with one room being slightly on top of another.
From the downsides - the biggest one is the entry door. There are 4 doors with the code locks to be opened. The 3rd one has a very poor lock which is barely possible to open. You could spend 15-20 minutes in front of it trying, before it finally lets you in. The worst of all - it makes so much noise, and the walls shake when one tries to pull it. At one night, someone staying in the neighbouring flat was trying to get in at 2 am at night - and woke everybody while trying. From the reviews it looks like we're not the first ones complaining about it.
