Key access was a big problem. Our arrival was not Ondra's priority. We only ever met Ondra. Ondra left the key in a public cafe about 500 metres from the apartment with only basic instructions on how to find the cafe. Once I found the cafe after stopping at 3 other places, the cafe staff knew nothing of the key. I therefore had to contact Ondra through AirbnB which took time. Ondra finally showed up with a key. My wife had to wait alone with our luggage on a Street corner in a strange City after we had travelled 6 hours to arrive at the apartment, not a good impression. Note we had booked in May so Ondra knew for months of our arrival and I had to prompt him on key pick up instructions the morning of the day of our arrival. Once in the apartment there was no internet or TV signal for 3 days and after getting the internet and TV signal working the TV on/off remote did not work. Ondra admitted he needs a new TV but did nothing for us to obtain a new one. Be aware that the closest streetcar is 500+ metres down a big hill from the apartment and the subway is at least 1 kilometre from the apartment. We are quite mobile for seniors in our 70's but anyone with mobility issues needs to be aware of the distances to public transport. They do have a very nice apartment as advertised. We would choose another location if we ever travel back to Prague.
