We arrived a little ahead of check - in time, but this was not a problem. We were there for a week, due to a conference and the stay was pleasant and comfortable.
The service personnel were extremely helpful and any requests were quickly met. The rooms were clean and tidy, with a decent amount of space and the attached bathrooms were very functional, clean and spacious.
The breakfast was adequate, although the menu was a bit repetitive and homogeneous. Unfortunately there was no option of requesting specific dishes.
There was no air conditioning in our rooms as we had neglected to request this option to my understanding, and the weather was very warm - but the rooms remained pleasant and cool through out.
The major downside of the hotel is its location. To get to a decent restaurant one must walk at least 30 minutes, which after a hard day of work is not the greatest thing to look forward to. It is also right in front of a rather busy road, and with the windows open it can be fairly loud.
The train and tram stations are nearby, and its easy enough to take one of these options to Sopot or Gdansk city, where there are plenty of dining and nightlife options. However the trains can be a little erratic, especially late at night.
Overall the experience was good, and the prices charged were very fair. I would highly recommend this place, especially if you look ahead for dining / entertainment options in other parts of town.
