Casa Republica is the ideal place for any international student visiting Santiago!
I stayed in the house for 4 months during my PhD; I would suggest it for medium-long stay.
All the rooms are well equiped and comfy. The shared areas are mantained clean and are big enough to happily share the time with the other flatemates. This element is one of the best points. You will have the possibility to meet people from all over the world, and share the experience in Chile; it is expecially good in case your spanish (or chilean!) is still not enough good, because most probably you will have also the possibility to speak in english and learn from the others.
The pictures well represent the real house appearance. The living room has a Smart TV, with included a Netflix account. There are machines for the laundry for free use. A dedicated space in the kitchen and in the fridge will be researved to you.
The Barrio is calm; at walking distance there are nice small restaurants and good supermakets. It is close to many universities (in particular, Universidad de Chile - Ingegneria). It is easy to reach the closest metro station (less than 5 min walking), and it is possible to reach the downtown area also walking (around 20 minutes or so).
It is also close two a park.
Clara is always fast in the answers and available to requests; Marisol is really kind and always make you feel welcome. I am really greatfull for the hospitality.
Hope to be able to visit Casa Republica again!
