I am old and have stayed in a lot of hotels. This is one of the best. The basics are all fine - comfortable bed, good modern bathroom, no street noise and good sound-separation between rooms, always clean and bright, desk managers always knowledgeable and helpful, excellent central location in pedestrianised area with supermarket, money exchange, coffee shops. Belgrade itself is very interesting, but there can be challenges with taxis/Uber/Bolt, phone service, currency, and streets labelled in Cyrillic script. The desk managers know the answers, they will spend time with you solving your problems (even if the problem is actually your fault). I would go back tomorrow.
