I've gone to more tutors than I care to admit - whether it be in the States, Bolivia, Costa Rica, Argentina, or Uruguay. My favorite tutor, by far, is in Montevideo.
You will not want to sleep (like in the picture, clever yeah?) when taking an individual (or group) class with Leticia. She makes you feel at ease, test your knowledge, and she really enjoys helping others. If you are looking to learn some Uruguayan Spanish, get hold of her...you won't regret it. $7 an hour was her individual rate.
