For the longer answer, your sentence should read, "The students and I enjoyed . . . ." Or, alternatively, ". . . was enjoyed by the students and me."
According to my dictionary, "myself" is used as an intensive ("I went myself"), as a reflexive ("I hurt myself"), or as a quasi-noun meaning "my real, true, or actual self" ("I am not myself today"). Your sentence does not follow one of those patterns, so the use of "myself" in your sentence is incorrect.
(You could have said something like this: "The students enjoyed . . . . I, myself, however, didn't think it was that good.")
