The Red Line we took yesterday at many stops the bus sat there many minutes after the passengers had boarded . When the bus got to the road the water was on it went very slow, which to some part I understand. But at the stops it continued to stay at it way after the passengers had boarded

The only complaints we have is that we did not receive our Black Friday discount of 15%. Audio guide not great, could put in a bit more effort. On the plus side Baltazar our walking guide was fantastic. Gerry Collins

It was ok.

It was ok! The Hop on Hop off ends at 5:30 at stop 1 and we had walk back to our apartment which was closer to Stop no. 2.

Easy to get on and off. The app is great for finding the stops and seeing where the next bus is on the route. Covers a great deal of the city so you get a wide range of sights to see.

The audio in some seats did not work properly. The explanations of sites was adequate but can be improved.

Easy way to explore the two cities in a half day. The narration could be a little more comprehensive. The red line is more interesting then the blue line as regards to sites and narration.

Very enjoyable and covers everything we need to see. Well done

Die Rundfahrten ermöglichen einen groben Überblick über Porto, Linien haben zu wenige Haltestellen, hop on hop off an den Sehenswürdigkeiten nicht wirklich möglich, man kommt nicht nah an die Sights dran und die Audioguidetexte sind langweilig, zu wenige interessante Infos, Beschreibungen, belanglos. Das nächste Mal öffentliche Verkehrsmittel Tagesticket Andante Azur, Geld gespart und individueller.

Previous Hop on Hop Off in other cities would announce the stop and what could be seen with this stop. For most of the stops, the drive just stopped for a moment and then left with no announcement. Often the stop was so quick, that someone upstairs would not have time to get to the exit. Poorly done.
