A friend and I stayed here during a short weekend trip from Sweden. We were picked up at the airport by a extremely friendly young man who made great suggestions about what to see and do during our visit. He even called a restaurant to secure reservations at the last minute. All of the staff was just as accommodating.
The hotel is very beautiful. It is not large and impersonal, but neither is it cramped. It it very modern, but not oppressively so. The views from the water side of the hotel are beautiful, and definitely worth the upgrade.
The rooms are spacious (US-sized, not Scandinavian-sized) with beautiful, natural hardwood everywhere. There are subtle elements of traditional Estonian craftwork in the appointments. They have tubs in the bathroom.
The breakfast is very ample, catering mostly to Finnish/Swedish guests. It can get quite busy during peak times, but it is not overwhelming.
The location is quite good, but you will have to walk 2-3 blocks to the old city; however, there is a full grocery store and shopping center just across the street.
I would highly recommend staying here.
