This is a nice place if you want a peaceful weekend! There is not internet (your phone won’t work in spite of you have gigas in it), and only in hotels, you can find wifi.
There are a lot of pools where you can take a hot bath, the pools have different temperatures. The “sopa verde” (green soup) is the best dish! You can find it in many restaurants and at night many street vendors can offer “Muña” that is a beverage to keep you warn and good for your stomach. (They sell it in a plastic bottle)
Also the candies like Cookies with manjarblanco is delicios too!
The weather is not cold, however there was raining, so don’t forget your umbrella or jacket with hood!
It is enough a full day there! You can find many hotels and hostales there!
