Buenos Dias!
We are in the search for hosts in Uruguay. In the present we are leaving La Paloma on our way along the coast to Chuy and later inland towards Artigas. Give us a shout if you want to host us! We have a tent with us.
Have a nice day!

Try using the search feature, find some hosts that have a history of replying to requests, read their profiles and make a thoughtful, personal request if you would like to stay with them.
For zero effort requests posted to anyone in particular see Couchsurfing.
