Ondrej’s place is great. A very cool old building with antiques and a vintage vibe. Despite being so close to Wencelase Square the apartment was very quiet at night. The bed linens were nice and warm and the bed was comfortable. You can easily walk to any of the main tourist locations and transit is steps from your front door. You will need to walk up two steep flights of steps but that was no problem for us (even though I always overpack haha). The apartment was very clean and had everything you would need regarding kitchen and bathroom amenities. If we are lucky enough to come back to Prague we would stay here again.
