This hotel was completely overrated and I would not stay here again. It was not a bad hotel but is rated far too well on Tripadvisor and the rating is misleading.
We had a horrible experience booking through Expedia and had to stay at another hotel the first night of our trip. Once we finally checked in, we were disappointed by the room. It was slightly worn and needed updating. Breakfast was mediocre and the pool/pool area were nearly non-existent.
The positive attributes were the view of La Rambla and the location in Punta Carretas/ Positos. (It was a quick taxi ride to downtown.) The restaurant La Perdiz was in close proximity and fantastic!

Me and two partners of the Governmental Institution where we work in Argentina, were invited for a conference in Montevideo (Uruguay), one of us as speaker.
For that, we've rented 3 rooms for each. But when we've arrived at the Cala di Volpe, members of the hotel tell us that we couldn't have any room because all reservations were closed because of some problems in the pipes. But, nobody, advises to us about that problem, previously by email.
The most anger came when nobody gave us any logical and responsible answer and when nobody tried to offer us any solution. After an hour of discussion, the offer was to move us to another hotel at 30 minutes from the place of the conference (Sheraton Hotel). Finally, after 30 minutes more, the hotel's manager appeared and offer us to put in the Sheraton Hotel. That costed to us more or less U$S 40 more for each one, adding U$S 34 to obtain 2 days of wi-fi connection to work, comparing with the free internet at Cala Di Volpe.

The Cala di Volpe is the place to stay for tourists who want value for their money and can live without the bells and whistles major hotel chains may offer. We can recommend this hotel because we live in Montevideo and stayed here once when workmen performed maintenance on our dwelling. We also have relatives who stay here when they visit us. In addition, my company has made reservations for business contacts to stay at the Cala di Volpe. .

On the plus side, the rooms are nice. Try to get a suite, usually on a higher floor. These aren't huge, but they are a bit bigger than standard rooms and are decidely more comfortable. Room prices usually include a good buffet breakfast. The restaurant offers a good selection and includes local favorites, like "locro stew,"usually served during the winter. During certain months of the year, the hotel gives an afternoon tea.

Be aware that service in Montevideo, while polite, is often slow. People here are not rushed. Accordingly, the drink you order in the hotel restaurant can take a half hour to arrive, even if you are the sole patron. Dinner may well take a lot longer. I attribute this to culture as well as "multitasking." At least the staff is friendly.

The Cala di Volpe offers a lovely view of the ocean-like Rio de la Plata, and the Ramblas, a pedestrian path along the river which the whole city seems to use to bike ride, jog, walk, or picnic. The hotel is located in the middle class neighborhood called Positos. A nice steakhouse called La Perdiz (the Quail) is a two block walk from the hotel and a shopping mall is 4 blocks away. One kilometer brings you to the golf course.

If you don't mind a small pool and gym, you will like the Cala di Volpe. Travelers arriving from Buenos Aires who travel on a Buqubus ferry boat should contact that company about packages that may included more favorable hotel rates.

We stayed here 2 nights and thought this was a great hotel. The front desk was very helpful and the location was great. It's not the city center but it's a very affluent part of Montevideo and is right on the ocean/river and a short walk to some nice beaches. We took some very nice walks along the Rambla and also walked to the Punta Carretas mall which was only a few blocks away. We ate at La Perdiz, also a short walk, and had a great meal. The croquettes de lomo (tenderloin skewer with peppers and onions) was wonderful. The rooms were a little small but nice and clean. Breakfast every morning was nice and we also had the afternoon tea one day which was also good. I would definitely stay here again.
