We stayed at this place for two nights and greatly enjoyed it. This is a modern hotel with helpful staff and very comfortable clean rooms, most of which come with a clear sea view. It also has a well-sized swimming pool (diving is allowed) in a nice surrounding area. Breakfast is well above average as far as Lesbos hotels are concerned.
Those offered ground-floor rooms (read semi-basement, no balcony) and people without their own means of transportation are likely to come out less satisfied with this hotel than we have been, especially since the beach in front of the hotel is stony. Another factor to consider is that this hotel was built in several stages, meaning that some blocks are considerably older than others.
Overall, however, this place is definitely worth considering if you are staying in the Molyvos area. Just make sure you secure one of the better rooms and, if possible, a car or scooter.
