The surrounding town is not very nice (Lujan) if you are the type to want to go for walks and runs in the area. While we didn't have a car and managed fine with taxis, it was a bit challenging to get to the grocery store and restaurants. I'd recommend renting a car if you will be here more than a couple days - the taxis definitely added up. There is a but into Mendoza that takes about 45 minutes and Nacho will drop you off at the bus stop, but to take it back at night is a bit sketchy.
Since I booked the reservation, the owner, Nacho, could not have been more helpful. He booked all of our wineries visits, bike rentals, mountain tours, and even bought our bus tickets for us from Mendoza to Bariloche. The B&B was incredibly spacious and comfortable - the biggest room and bathroom we had. The bed was incredibly comfortable. Grounds are beautiful and inviting if you feel like relaxing at the hotel for an afternoon.
