Hotel is pretty ok especially for this price. Staff is very helpful and nice. I was also informed by staff when I can expect crowd during breakfast and when I don't need to worry. I've not asked about this but it helped me and I ate comfortably when most people already left :)
Of course it is only one star hotel, so the interior especially walls etc. is not in the best condition. On the other hand bed, and desk was new. It was also very clean and warm (even a little bit too warm). The breakfast was very good especially when I compare even with 2-3 star hotels. You can choose from 3 different bread types, scrambled eggs, boiled eggs, fried sausages, 3 types of meats, 2 types of cheese, tomatoes, cucumber and few other vegetables. Milk, flakes, coffee, tea and so on.
The only issue in this hotel is other people staying there. Lot of noise, loud shutting doors and loud talks and parties on corridor. This unfortunately might happen in any hotel, but here you don't have any silencing doors, walls etc. The thing is that you have in one place 3 different hotels: 1, 2 and 3 stars with different prizes, and this one is the cheapest, so there is always lot of people here, also students etc. Fortunately I had earplugs so just after few minutes I fall asleep.
Good value for short stays in Warsaw.
