Language barriers with a few of the staff. This is understandable, the problem is how they handled the situation. It was like they ignored or snubbed me and I was standing there not knowing what to do because I was sure they heard me. It took a while for me to realize that they either are not fluent or dont speak English. Note however that most of the staff can speak english. I only happened to have encounter with two who are not quite fluent on my first day - electrician and cleaner. Im sure they didnt mean to make me feel snubbed.

Amazing food, comfortable bed, very accommodating staff. They also have sauna, pool and gym - good break from a busy workweek we had in Belgrade

Inner swimming pool very cold, not confortable at all; Small room. Hotel not appropriate for small children, should be labelled "adults only". There is no wheelchair/stroller acess at the main entrance.

Very good Breakfast. Spa with good services. Staff very attentive and nice.

Everything is just right at the Square nine Hotel: perfect location and service, great architecture, very good restaurants. We had three rooms as a large family. We were kindly given an upgrade. We'd love to come back and will be advertising it in Berlin.

Absolutely nothing to criticise!

Absolutely loved the hotel! Perfect service, incredibly friendly and competent, on top of super design. Wish one could find hotels like these in other European cities. Also wish my business would bring me back to Belgrade more often, so that I can stay at the hotel... :)

We didn't like the fact that you were allowed to smoke indoors. As non-smokers, we found it horrible. But we understood, that this is the case everywhere in Belgrade. A shame, I hope the law changes soon.

We absolutely loved out stay. Staff was fantastic! We will be back soon! Everyone was super friendly and doing an excellent job. The atmosphere was cozy and clean and detail oriented. We loved it.

Overpriced. Breakfast included in room rate is just rubbish, you have to pay over to have just normal breakfast.

One of the best designed hotels I have been to. Nothing extravagant, but you feel so well in these interiors. Location is perfect. Food at the breakfast was very good.

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.

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

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!

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!

Would be good if there was complimentary water in the rooms or a least for checking out/checking in at the reception

It was really good experience overall

A little bit of noise could be heard from the street side.

Fantastic location , beautiful design & friendly staff.

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.

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.
