The Ernst Hotel is in a prime location in Cologne, right next to the cathedral, a few meters away from Cologne central train station and within walking distance to the Rhine and the historic old town. The rooms are comfortable, mini-bar included and excellent service from the hotel staff, which is, by the way, multi-lingual: there were staff speaking not only English and German, but also Portuguese, Spanish and French. This was my third stay at the hotel and I strongly recommend it!
