We had an outstanding stay at Hotel Geronimo in January this year. The staff is simply amazing!! So helpful, social, and kind people :)
The room we stayed in was very cozy with a nice queen-size bed, a relatively big closet, a cozy balcony, and a nice and fresh bathroom! There was a TV with a variety of channels, and the rooms are cleaned every day.
We stayed there with my 2 year old sister and they were so helpful, very child friendly! Since our room was on the second floor, they let us keep my sister's stroller in a room downstairs so that we didn't have to carry it up and down the stairs every time we went out. They did also let us have all of our luggage in that same room on our check-out day so that we could spend a nice last day in Pucón without having all of our heavy suitcases with us.
The breakfast was also very nice, it isn't Hilton class of course, but it had different kinds of bread with a variety of things to put on it; Chilean manjar, jam, butter, cheeses, ham etc. There was also hardboiled eggs, scrambled eggs, coffee, tea, different kinds of juices, different kinds of fresh fruits etc. So it was a very nice breakfast for the price that you pay to stay there! They also provide a "take-away breakfast " if you take an early trip (before breakfast starts) to the volcano for example, like my mother did. The staff made some nice sandwiches with a drink for her to have on the volcano trip :)
The only thing that I could say is on the negative side is maybe that the WiFi didn't work in our room. On the other hand it worked absolutely perfect in the lobby where they have cozy sofas, and we had the TV in our room so it wasn't the end of the world really.
If you go to Pucón, I really recommend Hotel Geronimo!! :)
