My grandpas work

This is hotel in Prague, the architect was my grandfather Jaroslav Trávníček. He win competition in 1979 and they took his design. Personally i dont like this much. But in the time this was developed this hotel was at the peek of Czechia architecture. I want to know your opinion on this building.
