I am in Warsaw a few times per year. The city offers a big choice of hotels. From time to time I decide to stay in Campanile. Especially, when I come to Warsaw by train, it is quite convenient to get to the hotel from the main train station called Warszawa Centralna.
However, there is not a problem, except traffic jams in Warsaw, to arrive in the hotel by car.
The hotel is located almost in the very centre. It is even possible to go to old town by foot.
I advise to book hotel either via booking.com or direct on campanile.com. It is much more cheaper comparing to the prices offered in the hotel.
Campanile in Warsaw , similar to that one in Szczecin seems to be one of the oldest hotel of this chain in Poland. Rooms are spacious but furniture is rather used up, especially hangers and looks simply old.
In the room you will find a tube TV, however hotel has quite good offer of TV channels like Canal+. Bathroom is also clean and practical.
Breakfast like in other hotels of that chain – simple but sufficient, so there is a choice of hot (sausages and scrambled eggs) and cold food, fruits, cheese.
The hotel also have a kind of restaurant. It happened once that I had there a dinner, but I don't recommend it. In the vicinity of the hotel there are many much better places to have dinner or lunch. In addition, prices in the hotel seemed to be high.
