The sentence is in the present indicative tense. This tense is used to express habitual actions or general truths, so Eu durmo bem. implies that sleeping well is a regular or typical state for the speaker.

Why is bem used instead of bom in this sentence?

Bem is an adverb that describes how the action is performed, in this case, how one sleeps. Bom is an adjective and is used to describe nouns. Since we are modifying the verb durmo (I sleep) rather than a noun, bem is the correct choice.
