We stayed two nights at the Inti Wasi Lodge at the South Side of the Isla del Sol. It was not so easy to find and therefore a little boy who we met on the way showed us the Lodge. But be careful not everybody who wants to show you a place on the Island really takes you to the real one you are looking for.
So just an advise the Inti Wasi Lodge also has a Restaurant besides the huts which is called palacio de la troucha or something like this.
The view of the little cabanas is really really great. You could see a wonderful sunrise just from your bed. So you don't have to get up so early in the morning *g*.
The private bathroom within the cabanas was really clean. For sure they don't have hot water, because there is a lack of water on the whole Island as far as I know.
The host seemed to be a little rough. A lady which exactly knows what see wants.
For example the breakfast time is from 6:30-8:30 and on the second time she knocked at our door already at 7:45 to say that it is the last chance to get breakfast.
We payed 70 Bolivianos each, breakfast included, but we had to bargain a little.
I think the breakfast is not worth it because we just get a quite old and already a little hard bread with jam and butter and coffee or tea. Really nothing special.
In the meantime there are many many shops at the Island where you can get a cheaper and probably better breakfast.
All in all we liked the Isla de la Sol but in the meanwhile it became really touristic so all the people living there want to make money with you. So be careful!!
