"Alex and Tanya" are actually a company which rent many appartements in Prague and turned them into Airbnb. They have an office 20 minutes walking away, where you need to pick up the key yourself. We've had some parking added, and the parking garage was 1-2 km away, so that worked out quite well except of that it added lot's of driving back and forth in a narrow, very busy city. Parking at the office, where one needs to pick up the key is almost impossible. Because you need a special card-key to get your car back, you can only get your car back within the office hours, which is earliest at 09:00 AM in the morning. The apartement was really clean and had everything that was promised. The contact was very quick and reliable, so that any questions were answered very fast.
