I have a single room at 2 blocks from Tobalaba metro station. That is a very good location at Santiago at Providencia district. There are also a lot of buses next to the place.
The place is quiet, but very close to all kind of services, there are supermarkets, minimarkets, restaurants, food to take away, a Mall and places to go out at night and party.
The flat is cozy, there are only 2 rooms and the other is my room. The bathroom is shared with me. The bedroom is comfortable and has a drawer to put your stuff.
There is a nice balcony to enjoy on sunny days.
The apartment is fully equipped, the kitchen is available and you may even wash your laundry if you bring the soap.
I can tell you about nice places to visit, and even we may do something together if you want to.
