The bus to Salzburg is only 15 minutes away, but there are several buses going at the same time, and Hellbrunn or Cable Kata are both on the mountain, so if you have a timetable to go there, you can stay in the hotel, especially if you travel from Take the Flix or Leo bus in Prague or elsewhere. This is the direction from the station to the city, so you can find accommodation earlier because the accommodation is earlier than the city. The staff are friendly and it rains a lot in Salzgan, so I rented an umbrella from the hotel and used it well. The disadvantage is that it is air-conditioned, so I chose this type of accommodation, which is usually not what we think it is, but a fan-like device.
Please note that air conditioning is installed. However, it rained on the day we went, so that air conditioning was not needed. Opening the window and blowing the wind is much cooler than opening the air conditioner. You can open the window, because there are no mosquitoes, it doesn't matter. In addition to the disappointment with the air conditioning, the price is cheaper than the accommodation in Salzburg, so you can take the bus.
