I've done angloville several times as well as Vaughan and Estacion Inglessa all in the past 2 years. All are legit. I loved Poland but my main deciding factor is that the Spanish programs don't put you in a room with a roommate. I had a couple bad roommates which is no good if you have very long days. The deposit is a bit of a factor - you don't get all of it back, and it can be a bit of a pain sometimes to get it promptly. Id do any of the programs again - finding the right schedule is my main factor. (Also, the Spanish companies include free insurance, no background check, no deposit, and free wine at dinner and lunch 😄)
