Academic aspect = poor, social aspect = amazing
Pros
The location is breathtaking (on Lipsi Island), when situated at the accommodation near the main part of town. The friendships you make are life-long, such great people to work alongside.
Cons
Horrible company. Taking the governments money for their "initiatives" and no positive change to the environment is seen. The patches of sea grass replanted all died. They do not have dolphins btw. All very misleading. Most online posts are false advertisement to make it better than it is. Volunteers are rarely on boats, in the water or conducting active research. The management exploit you for your skills and will not help you achieve what you went there for. They will promise you promotions but never respond when time comes to it. So much cleaning and feeling isolated when staying at "the Sanctuary". You get into trouble when you are not working thoroughly. 9-5 working hours, minimal food. The accommodation + food is way too expensive for what you get - they try to make you feel bad when asking for more food/more protein, saying it's an island and we should lower expectations. An absolute joke.
