On the positive side, this apartment was comfortable, clean and located in close proximity to the Palace of Culture and Warsaw central station. It also had easy access to various supermarkets and restaurants, along with a lift to the floor.
On the less positive side, and the reason why it does not get five stars, is that you have to travel to a location 30 minutes away to get the key, they had not set up beds for our two kids, and the fact that they only had one cereal bowl, which made breakfast a delayed affair.
If I returned to Warsaw, I would not mind staying here again.
