We stayed at the hotel Aeolis for two nights.
This was such an enjoyable stay.
The room was clean and tidy and the beds were comfortable we certainly had no complaints.
All the staff at the hotel were so pleasant. The staff were friendly especially the girls at reception who always had a smile and were very helpful.
We live in Kusadasi, Turkey and when we come to Samos again we will certainly stay at the hotel Aeolis.

Booked as part of a Thomson deal (£370 flight ex UK + 7n B&B).
The location on the front in the middle of the action of Vathi is good if you are without a car. All the amenities are close by. That means of course that it is a busy area with traffic and bar noise part of the expectation.
I found the desk staff (eg Rania) friendly and helpful.
The room is a good size and large bed (even though booked as a single). A hard mattress, but ok for me. Aircon working but only just. Bar fridge and free WiFi in the room was useful. I had a room at the back which still had some bar noise until about midnight but the double-glazing eliminated it. Decor old-fashioned and small but clean bathroom. The shower rose kept leaping up from water pressure so had to be hand-held.
Breakfast from 7-10am is good - cereal, yoghurt, fruits, breads, eggs, sliced meats and cheese. The bar at the front was very popular as it is pretty central to the "strip".
Rooftop pool is adequate and clean and gives great views across the harbour.
Lots of eateries nearby and an "Atlantic" supermarket next to the church up the hill East of the hotel.

Our ferry schedule changed, so we had to spend a night in Samos. The room looked worn, though the location was close to the ferry port-which was nice. I would recommend with caution.

Unfortunately I chose to stay at this hotel for one night as it was close to the harbor that I was supposed to leave from there the following morning. As I booked a room with a front sea view, I realized from the first moment I entered the room, that the heat inside was profound. When I asked about the air-condition, they told me that they had to shut it down, as the weather was changing and the system couldn't decide on which mode (cold or heat) should function!! ( a very cheap and totally unacceptable explanation as most of them are able to function on a certain mode). As I thought to have a walk around the town, when I returned back to the hotel to rest during the afternoon, the heat inside the room was unbearable. From the other hand if you dare to open the window, the noise from the front road, where cars and motors are passing throughout the day, makes you feel like living in the centre of a big city. Finally in the evening I complaint again to the reception about this and they gave me the same response. The receptionist though, being kind and friendly with me, she told me that she would help me to put the air-condition on fan mode ( though I was expecting to be transfered in a more calm room than this one). Finally even this option was not adequate to deal with the heat of the room and the noise during the night was even more, due to a very popular coffee bar in the front of the hotel, full of young and teens and with loud music.
I really regret that I chose to spent my only day in Samos at this hotel, as the whole situation really ruined my accommodation there. I would definitely have chosen, knowing this, to stay in a more peaceful place out of the town in front of the sea, since I had rent a car. Definitely not recommended for those who choose to spend their holidays and enjoy the sun and the sea.
It's really a pity, otherwise this hotel would gain a better review, since the room was convenient enough, clean and tide. But for such hotels the proper function of an air-conditioning system is absolutely necessary.
