The tour is an excellent option to see the city. One complete circuit takes about two hours, and another one hour if you take the cable car and funicular which offers very. The frequency of the buses is around 25-30 mins. The operators are well organised and the commentary was apt and understandable. Get Your Guide instructions are outdated as there is no need to exchange the voucher for a physical ticket at the only one pickup point listed. In my case, the operator sent an eticket by email and whatsapp, and the bus staff scanned the barcode anywhere I started. You can even buy the ticket on the bus by credit card if you have no prior booking. The only problem that I encountered was that there are no signs to indicate the stops, as is usually done in all other cities. So you will need to remember where you got off to catch the bus again after a stop.

Pretty Good. Take you to all the tourist stops, has a map that is helpful for you. You get commentary via automated system in your language. (Wish the headphones they give you had longer cords not really usable if your sitting on an isle seat) One thing where you have to ask is that their maps for pickup point is wrong is at the "Funicular" (Hope I spelled that right) if you take the cable car up and the Funicular down the map points you a few blocks away but the real pickup point is at the entrance to the Funicular. A lot of restaurants there for lunch.

On the first day I used the ticket, I followed the instructions and went to the starting point of the tour. I was given a number and told that I may not be able to get a seat on the next bus, as people may not get off. Luckily I did get a seat on the lower level, but the windows were covered with tinting; you are unable to take any pictures unless you are on the upper level. Other than this, I got off, see sites and got back on, with a view at the top!
