I stayed for only one night, while on a customer visit in Tallinn. I had stayed at Olumpia a couple of years earlier and the hotel was as good as I remembered it.
The room was quite small, clean, with a modern interior and had a a very nice view of the beautiful Tallinn city. As far as I can remember the Internet wifi was free.
The front desk was really good, with several employees helping with check in/out, quick and friendly service.
The breakfast was good, normal Scandinavian / Baltic kind of breakfast with everything from smoked salmon and pickled herrings to scrambled eggs and sausages, everything was very fresh and clean.
The location is downtown, it takes only about 5 minutes of walking to get to the Old City with all the nice restaurants and pubs and the surroundings felt secure.
Overall a pleasant stay. The hotel has a fitness center on the top floor which is supposed to be good, but I never had the time to try that one out.
