Excellent hotel
We stayed 6 days at the Wilton on Vacation. The staff was very helpful in arranging tours and tango theaters. It is centrally located, walking distance to the heart of town or in the Recoleta district. We also took the subway to Palmero, which was very easy. I gave the Wilton a rating of 8 and not higher due to the fact it does not have wireless high speed internet. You can buy 2 hours of use from the front desk and must use it in the lobby. Just 1/2 block away is a cyber cafe we used.
All in all it was a good value for the money.
