great hotel and staff, central, easy access to everything

breakfast was included in the price and then to find out that it doesn't include scrambled eggs and salmon, or for that matter anything that you order from the menu they provide is beyond ridiculous for a 5 star hotel. So to summarize you are charged 20 euros on top off 30 they already charged for breakfast when booking the room, in effect those scrambled eggs and side of salmon were 50 euro.

Being a Genius Level 3 guy on booking, I have hardly ever left a 10 star review in the last 10+ years of leaving reviews across Europe and beyond. This hotel however truly deserves it and how! There were three of us with three superior king rooms. The location is great and it's truly the city center with access to clubs, nightlife and pubs. The staff is one of the most helpful I have seen. I don't remember the last time concierge offered to take my luggage to my room in Europe. Nothing ever was a problem. When we left the hotel, there were people to hold the doors for us. We truly felt pampered. The rooms were spacious with a lot of natural sunlight. The bathrooms were good size and looked rich and truly 5 star. The amenities were all high end. The spa facilities were amazing with a long swimming pool. I had forgotten to take my swimming googles but was offered one free of charge. They even had sauna and steam rooms. Finally, a special praise is reserved for the guy who served us breakfast (apologies can't remember the name). On the second day he remembered what we had ordered the previous day and even helped us in recommendations for the city. He went over and beyond in being truly helpful. And the breakfast was sumptuous and excellent.

Very minor in the grand scheme of things, the hotel would do well to invest in a bit of upgrade to the common areas and the furnishing of the rooms. Some of it looks aged. But it more than made up for it with everything else really.

Amazing location lobby and swimming pool. Kind staff. Beautiful location and tasty food. Convenient parking.

Asked at night for some disinfectant (had a cut) and night staff was clueless. For a 5 star not great. No electric plug in the lobby that is a bit absurd as many people working there.

Large comfortable room and shower, very clean. Good location

AC does not cool only heat so I needed to sleep 3 nights with open window which was noisy from the street during the night and early morning. Bed and Pillows are super soft which I did not appreciate.

One the best hotels I've ever been. personnel is so nice and polite, room is stylish designed, well-equiped and really spacious. Loved SPA and the restaurant! Would love to spent more time here!

Everything! We would give 100 out of 10 if we could. Very professional and exceptional service. The staff were excellent, friendly and attentive to detail and service. Japanese Restaurant was delicious.

Nothing at all!

Every time we travel to Belgrad, we stay at Square Nine. For us it' s the best place and service! I would also thank reservation service, maximum of help and politness. They work better than Swiss clocks!

The breakfast was incredible - great food, good buffet. The pool, fitness center and spa were AMAZING. I went every morning because it was so great.
