Firstly the hotel does have a great location, set mid way between the old and new town. Close to the port and across the road from Viru square where many bus services operate from. The hotel is a modern addition to the city and hosts a lot of conference trade which can make it very busy. As previously mentioned, it is better than the Viru hotel across the road where there did seem to be a lot of drunken activity in the reception area (along with a good proportion of the rest of the city come to that!).
Rooms were comfortable and very clean; beds were great! In fact the rooms were very well appointed. Initially had room 822 which overlooked an internal 'courtyard' so although very quiet had a view into the opposite corridor. After changing to 322 we had a room on the front of the hotel which overlooked the (noisy) road. Take your pick!!
Breakfast was busy busy busy, but offered a great selection of food and set us up well for the day. Staff were relatively attentive but like many other service staff in Tallinn, didn't enthuse welcome or helpfulness.
The 'spa' was ok although the swimming pool freezing cold and much smaller than the pictures depict.
A couple of times we went out and encountered groups of rough locals hanging about outside the front door which was off putting.
Not that we'd ever come back to Tallinn but if we did or had to recommend a hotel I think I probably would give the Nordic Forum the thumbs up.
