HI there, i have a farm 115km from Buenos Aires with a house w/complete services for you. The sourronding area is very nice for MTB, this is the Pampas region.
Im offering the place for travellers who would like to stay for a while (like 3 wks or more). If you are close or you think you will just let me know and i will reply with more info. Here some pics. Have a nice trip!
ps: this is no rental!
