Apartment was great! Highlights were the location, huge shower, and large windows. We were able to walk to most places, and the proximity to the U4 line meant we could also readily reach the main train station and other areas of the city. The apartment was clean and modern. As mentioned, the shower was huge, and there was a lot of counter top space in the bathroom as well. We did not use the dishwasher or washing machine, so I can't speak to those.
One note is that the pillows were so flat that even when they were balled up, they provided almost no head or neck support. Also, a lockbox of some sort would be ideal- while it was great to meet Peter's colleague, we felt like we were infringing on his time and if our train had been late, we would have felt bad about having to communicate that and change things around for them. If there was a lockbox, we could have entered on our own, whenever we arrived.
Overall it was a great apartment and superb location!
