It was my first time staying at Hotel Witkowski, and it was a bad idea.
The rooms are not soundproof, the receptionist said that they gave me a quiet room which wasn't as I could also hear loud music from outside of my window. There was no safety deposit box, and the beds were very low and hard. The shower is very cramped up. No wonder people are hitting the wall and having bruises from it. The service was okay, but I felt unsafe with them around a little.
The location was bad as there is nothing around the hotel maybe like one supermarket and one restaurant but it's away from the city centre. It is close to the Chopin Airport, and the hotel offers for free a shuttle van to take you there, but you need to book it.
The only thing I liked about this hotel was that you could spot planes every 5 minutes.
Overall,I would not recommend staying there.
