Jacob Said:

how long would it take to learn to speak and understand spanish perfectly?

We Answered:

2 or 3 years in Greece. 4 or 5 months if you move to Spain.
The good thing for a Greek speaker is that the phonetic systems in Greek and Spanish are very similar so that a Greek might pass as a Spaniard and the other way round if they learn well and if they're good with languages, as you told it is your case.

How long does it take to learn to speak fluent spanish?

We Answered:

The length of time needed to achieve fluency in another language varies. Some people can never achieve fluency in a second language, others are known to learn it in just several weeks. On average, if you study hard, you can expect to become fluent in two years.
The best way to learn a second language is to befriend a native speaker.
