I booked a bunk bed room and for me, it was great! The bed was very comfortable, there was lighting above the beds, blackout curtains and a good size mirror. I would say it may be a bit too small for a couple but for solo travellers it was great.
The hotel is in such an exact location, it’s right by the main square and you can walk easily to all the main sights. There are loads of restaurants and bars nearby also - I felt very safe!
The breakfast was ok - a cooked breakfast and continental. There wasn’t a lot of choice however it was definitely enough to fill up on for the day with a coffee machine and juices also.
If I returned to Tallinn, I wouldn’t hesitate to book this hotel again.
