We were a large group of 17 students from Sweden looking for a place to stay in Warszawa for a couple of days. Kanonia suited us perfectly! We accommodated three apartments. The apartments were simple but very clean. The location of the Hostel is extraordinary. Nearby there are several fascinating museums, as well as the royal castle which is beautiful. In addition, there are many restaurants and bars in close proximity. As for the service, the communication with the Hostel prior to and during the stay was good. We paid half the rent before coming to Warszawa and half the rent when having arrived. The first half was paid with an invoice which went smoothly and the second with a credit card. If you are looking for affordable accommodation in Warszaw at a central location, Kanonia is a good choice!
