I have nothing bad to say about So Stay Hotel. On the contrary, this hotel made my mom and I's stay in Gdansk so much better!
First of all - the reception we got from the staff, both when we first got there and during the stay, was professional and very friendly.
Second of all - the room. It was a good size (we could walk around and have our two luggages on the ground), clean and comfortable. Also, even though the hotel is situated near a rather busy road, we weren't bothered by any noise.
And third of all, the thing that impressed on us the most probably - the breakfast. We bought it from the start, expecting a humble, "normal" hotel breakfast - and got a huge buffet with scrambled eggs, wide range off toppings, freshly made bread and simply much more than we thought it would be.
So, also based on the service we got when we needed some things to our room, we really do recommend this hotel. Good location (walking distance to the centre, trams going to shopping malls), lovely staff, clean rooms. We loved our stay at So Stay Hotel!
