Good for those driving and do not want to go to city center.

Only cash. No credit card

This is a truly excellent place to stay at the listed price, probably because it is sort far from any real tourist attraction. We used it as a stopover before flying out of BA, but it is equally useful as just a place to relax, hang around the pool, play table tennis and stuff. The host is set on helping the guests in every possible manner, he recommended us for example a self-service car wash which we would have never dreamed of finding ourselves. The accommodation is incredibly spacious for three people and perfectly equipped. If we ever need to drive along RN7 again, we will definitely think of staying here.

The only real flaw is the general lack of reasons to visit Luján or its surroundings, which however in some sense makes the place the hidden gem it is.
