First of all, you get to the room, if you can get to the room whatsoever. If your key card works. Our cards had to be recoded on average 3 times a day. We stayed over three nights. And were also blamed for keeping our cards in wrong places 0_o.
We were hyped, mostly because of the location, but even if the location is awesome (mind you, by the train tracks and a very busy street), the rooms are not sound isolated anyhow, so you hear everything, inclusive the neighbors doors too. The positive was the AC, which was so loud it could to some extend deafen the outside noise.
The room itself was spacious and clean, but unfortunately you could admire the room even at 6.30 in the morning, as it was no way to block the light through the windows with the automatic blinds, which the hotel is so proud of.
You steer the room from the app in the phone that you get. Prepare that it will take 4 times as much time as normally it would without sucha funky system.
The breakfast was meh. Even though I got the best scrambled eggs (fresh to order) in my life, the rest of the buffet (monday, not many guests i guess), was dried out, sad, lacking and the opposite of inviting. The service was slow and somewhat unprofessional, no wonder much, as for what we understood they hire students (it's cheaper?)
At the check out we were offered the discount for our next stay, which we firmly declined. At this price point there are plenty of way better hotels available in Kraków.
