Sandra is Amazing, the location and the view was superb and we had a very good time.
Staying on the bus was a very unique experience and we stayed for more than 7 days.
My recommendation is if you want to stay for a couple of days , you should definitely consider Sandra's bus, but if you want to stay for more than that, try to consider other options too, as a shared bathroom, low lights at night, the comfort of beds, the outdoor shower and etc lose their appeal and start to wear you down.
Overall we had a very pleasant experience, we really enjoyed Sandra's company, and we learnt a lot about that region and saw a lot of beautiful places that we didn't know that they existed.
