I had a nice stay at theach Holiday Inn Express Cologne-Troisdorf.
Staff was friendly, the room was sufficiently large and the bed very comfortable.
Shower pressure and temperature were great,
though the shower head could have been a bit cleaner (limescale).
Bathroom was partially split and of good size.
Breakfast was extremely basic. One morning there was a savory porridge-like hot option (because of a tour group?), but nothing on other days. Hard boiled eggs were over boiled (grey-green yolk). Also on my final morning the mini croissants were only refilled after I had already finished.
Still, the breakfast is more than enough to get the job done, even if the choice and quality seems a throwback to yesteryears.
Just opposite the Hotel there is a Gas Station with a 24h Subway Sandwich shop, great for eventual nighttime cravings.
A McDonald's and a Steakhouse are also very close.
The location outside of Cologne is known beforehand so no fault of the hotel.
But, Troisdorf Spich is located just barely outside of the valid area for tourist cards such as the Köln Card.
It took me between 12-15 minutes of walking to reach the nearest S-Bahn station (Bhf Spich), through a quiet residential area. [Less]
