The living room is facing south (therefore not exposed to the sun) and the bedroom has an aircon which was perfect during the unbearably hot summer in Santiago.
The apartment is well furnished, has a proper kitchen with nearly everything one could need.
Location-wise it's a bit of a walk to the metro station or a bigger super market but it's very central and one can get anywhere quickly by bus.
Definitely would book it again if I came back to Santiago.
