Stayed at the Aegeon Hotel for 7 nights. Get a taxi there as the buses are a bit iffy from the airport as you have to change bus in Marcopolo. Connection could be anything up to 1 hour

The Hotel is in an idylic postion with all of the rooms facing the sea with lovely big balconies. Rooms very well fitted out, a/c, nice decor, good bathroom with soap, shampoo and shower gel etc.

Breakfast very good - hot and cold choices with tables looking up to the Temple of Poseiden - what a way to start the day. Took a stroll up to the Temple most days before swimming and reading.

Two Tavernas next door with traditional Greek food - calamares, souvlaki et al.

Hotel restaurant excellent Regular buses to and from Lavrio and Athens every hour at the top of the hill Sea and beach lovely - free beds for residents - good snorkeling and swimming but VERY busy at the weekend with locals which was fun. Always yatchs in the bay which was nice to watch in between reading and swimming.

No local shops but we liked this a lot as this was a switch off the brain week away. Not good for people looking for stuff to do

We live in Athens and we like to spend summer weekends in Sounio as it is really close to Athens and there are nice tavernas around. We usually stay at Cape Sounio hotel but this time, as it was a last minute decision, it was fully booked so we decided to try Aegeon.
The hotel is impressively located right on the foot of the Posidon temple, in front of a really nice beach. This, and the fact that almost all rooms have a sea & sunset view are the best parts of the hotel. Almost anything else ranges between average and annoying and it hardly competes as a 4 star hotel.
The building, dating back form the 60s, and is recently renovated.
Rooms are of average size and are decorated in a way which borders between "modern" and tacky. Cheap chinese reproductions everywhere with some personal touches here and there (copper painted wooden night table and shell covered ceiling lamps !) . Nice marble bathroom however but with absolutely no amenities.
The beach is nice. However, it is packed with 4 rows of umbrellas (although it is not that big) and about a trillion people and even more babies. There are babies everywhere, jumping, playing and crying all over. It is then that I realized that this is an open beach and everyone from Athens has access to it. You cannot help but intervene to other people's conversations as you all sweat together under the sun in one huge and loud party.
There is also a basic beach bar serving refreshments, beers and crisps accompanied with hideous "bouzouki" music coming out from a couple of really cheap speakers. At least the girls behind the bar were dancing and singing the lyrics passionately while they were serving the parents and their babies.
Breakfast was rather annoying with nothing but the very basic and of mediocre quality.
Finally, there is no convenience store for newspapers, cigarettes, magazines etc. in the hotel and the nearest one is 5-6 kilometers away.
Overall, I don't think I will ever go back there again, although that I would recommend it to parents.
There is absolutely no comparison to Cape Sounio which is 500 meters away but is double the price.

The hotel is in a wonderful location, with views up to the temple of Poseidon and overlooking the small bay. The beach is not that great, pretty dirty most of the time we were there. Rooms are clean and perfectly adequate. Breakfasts were quantity rather than quality. The two tavernas on the beach serve good food, reasonably priced. On our first night the hotel's bar near the beach was packed until the early hours, on the next day it was shut at seven. Given the rave reviews we were expecting something rather special and the Aegeon is not special in any way that springs to mind. Very handy for the airport, as many other reviewers mention, although its not exactly round the corner.

The hotel is in a fab location.The staff are very friendly and nothing is too much of a issue !! Excellent choice will def return back for anoher vacation.
