Starting off with the positives, the hotel has a great location near a beach in La Barra, and a nice-looking territory.

I should have gotten the hint when I was making the reservation. Almost none of the staff speaks English, and simply making a reservation required a very complicated series of emails and international phone calls that lasted more than a week. The inconveniences were to continue when I arrived, which would be fine for a $80 hotel, but not for $120 (which actually increases to $320 the week after I was there). It's an understatement that the "decor doesn't seem to have been updated in a very long time", as another reviewed put it. It is antiquated, and not in a good way. Various shelves and doors are difficult to open and close, the door key is a very cumbersome, annoying mechanism, water sprays everywhere from the facet and shower, and the dubious, unappealing tiles on the floor are still from the 60s.

Only two people from the staff spoke English, I think. I don't know about other hotels, but every restaurant in the area was English-speaking. Breakfast was a very complicated affair in which the incompetent waiters stood there without telling me what was available. I had to guess. They made mistakes with orders, couldn't remember what I liked from the previous days, placed things on the table in a cumbersome way, and it was hard to get their attention.

We stayed at La Posta in early March, 2009. Overall we were very pleased with out stay. It is a great location in La Barra . It is right on the beach and close to shops and restaurants. We were very happy we did not stay in Punta del Este (a mini Miami Beach). La Barra has charm and is convenient to Jose Ignasio and futher places north. You need to rent a car to enjoy this area. La Posta was a bit dated but the rooms were comfortable and clean. The staff was nice but not great. The hotel restaurant looked nice but was very expensive and old fashioned. I would guess that a dinner for 2 would easily be $100+.

Not a whole lot of frills here, but you're steps away from shops, restaurants, a beach and surfspot; so what do you need? Pretty friendly staff, didn't really challenge them with anything but they seemed nice enough. Love the location.

The hotel is in La Barra. Only 10ks or so from Punta but in a different world. La Posta is low rise, with interesting architecture and a few yards from the sea.
We'd just hit low season when the room cost $120. In high season it's US$360.
Sea views, friendly staff, good food - when the restaurant was open.
But above all a base to visit Punta del Diablo a couple of hours up the coast. Worth a visit for its beachside huts and amazing laid back, one-man restaurant The old man and the Sea.
