Night choice
In a city hotel, the nights from Sunday to Monday are usually the cheapest: weekend vacationers have checked out, business travelers are still arriving.
Check-in
It's best to check in as late as possible. Standard rooms are often already booked, so there is a chance of a room upgrade.
Location and size
Ask at the hotel reception for a room on a higher floor, these are usually better - and further away from the street noise. Corner rooms are also worthwhile: they are usually the largest in the hotel and have more windows.
Social media
If you casually mention that you follow the hotel on Instagram, for example, and like to write reviews, you increase your chances of getting nicer rooms and better service.
Kindness
Being polite to staff should be a matter of course - and it pays off. There is often a small bonus such as a fruit basket or discounts.
