 Nothing except the location was a bit far than expected from the city center but a tram station was just opposite of the hotel with 10 15 mins ride Although tram access are only till half past midnight so if you plan to stay longer late nights in the city center then be ready to spend using cab or Uber which is an easy 10 15 euros per way 
 over all concept of the hotel was just a breathe of fresh air like mostly everything good for solo travelers and couples but not for the family as the room s are built for not for more than 2 persons Bed is too comfy there is just one day that i over slept and lost the day already cause the entire mattress will suck you in for a good reason Variety of breakfast was decent internet was fast Advanced TV and room access via an ipad a first i m well traveled and stayed in so many 4 5 star hotels but this one just puts it on the top Fyi self service check in hotel
