We stayed in apartment 14 for almost 3-weeks (although we did try to move to another apartment because of the noise issues, but without success).
The good points:
The air con worked well and wasn’t too noisy so it could be left on at night.
The blackout blinds in the main bedroom worked well and made the room very dark.
The bad points:
It was almost impossible to sleep and relax because of the noise; not only from the traffic on the busy road outside, but also from the Metro trains running under the apartment - the room would literally shake every time a train went under the building - we did complain to the landlord and to AirBnb but they were not able to offer us an alternative apartment without paying an additional €700 fee - the noise was so bad that we decided to pay to stay in a hotel for 3 nights and then ended our stay early (by another 3-nights) so that we could fly home and finally sleep properly.
There is no storage at all in the second bedroom (just two single beds). Nowhere to put your clothes. Nothing.
There is only a small table top ironing board, only really good enough for ironing shorts and t-shirts.
The TVs in the lounge and main bedroom are installed on the walls in ridiculous positions and can’t be tilted or swivelled. Made it almost impossible to actually watch the TV.
Overall, we would not recommend this apartment to anyone, and certainly not if there is more than two people staying in the apartment.
