I spent a wek in Poseidon residence and generally had a good experience. If you wish to spend more time in the old town and there where more things happend, propably Poseidon is not exactly the best choice, even there is a buss comming from center/old town(about 25 minutes). From buss stop is about 10 minutes walking to residence. Be awaire if you arrive after 20.30(is already darg), I recomend to take a taksi from center, can cost about 6-9 Euros, becouse the road from the buss stop to the residens goes frou the erea surounded by little forest and no houses, even it is about 10 minutes, it doe not feel very comfortable/safe, expecially when on the street is not lights and up to the hill. The feeling was, that you enter in the darg forest. I had to call to Christos to come down to meet me, becouse there was not any sign of the street name. On the day when I left Posidon, I called the taksi, waited for one hour and walked down to take a buss to the center to get to airport. Would not recommend to relay on taksi, if you scheduled your time in advance. Fortunittely my flight was late in the evening, so I had time. Christos was very friendly and helpful. Would apreciate if I could be tald in advance about this surprice in the night on the dark street. Thank you!
