Really great hotel, and surprising that it was amongst the cheapest I found in Cologne! The premises were clean, the lobby had plenty of nice areas for relaxation, including some modern table to charge your phone. The room was spacious and had a kettle, as well as a complementary water bottle. We cannot comment on the breakfast, because it was too expensive for us and we did not select it. Also the hotel is close to the Belgian Quarter which is very nice to stroll around, and relatively close to the tram station, However, if you come late at night (after 11) you will have to come to the hotel from the subway station nd this means passing through a very dark park, just a heads up!
Otherwise, really lovely selection of a hotel and would without a doubt stay here again.
