Not every driver activates the microphone, and then you can't hear anything. Another guest then asked the driver to turn it on so that we could hear everything. You have to know that you should report it, because many don't know that and then do this tour (without learning anything) because they think it's broken. On our other tours we saw again and again how people desperately stuck around with the headphones.. Maybe ask as soon as we get on if it's switched on.. !! We had over 35 degrees on the deck and it was almost unbearably hot, since unfortunately there is no shade, a roof or something similar would be very, very useful here, because if you stop and sit in the bus, the sun is beating down on it .. but that would only be a suggestion.... Otherwise I would do it again and again, the price is totally OK. and a great thing to learn a lot about your vacation spot .. really TOP!!!!

Very good, I think it's the best way to get to know the most famous places in the city in one day. the bad thing is that upstairs they don't extend the tent to cover the sun and downstairs there is no air conditioning and on a day in the middle of summer it is quite hot.

You can get a good overview this way. It was just very hot and there was no more room in the lower part of the bus. Unfortunately, the sound quality of the audio guide is very poor, so there is a lot of room for improvement. But I would definitely recommend it.
