I've stayed in many hotels by now and Vienna Easy stands out when it comes to all the colorful details in their interior design. It's not just any bland and boring dime-a-dozen hotel, but they have made a bit of effort to make it cosy and welcoming.
The room was compact, especially the bathroom, but I am not one who needs a particularly spacious room when I'm traveling. After all, a hotel room is mainly for sleeping and taking a bath / shower after a long day exploring the destination in question.
Which leads me to my one and only complaint; the air condition did not work properly. Sure, we chose to travel to Berlin in the summer, but still - is there an AC installed, I expect it to be fully functional and cool down the room as it's supposed to. So we had a constant temperature around 25 degrees Celsius in the room. In order to be able to sleep, we simply pulled the covers out and slept with sheets only. A trick that always works during heatwaves when there is no AC available.
Otherwise, this hotel fulfilled my needs. They offer an excellent breakfast buffet, as well as a good location around the corner from S-Bahn rail station Landsberger Allee, from which Berlin's excellent public transport network is accessed.
