I went with my friend to Zante in July and would definetely recommend Sandra's Bar. Sandra and Costa were very friendly, always giving out free shots and fruit with our order. They are not pushy like many bars. Sandra's bar is a great place to go at the end of the night for a chilled out drink. The cocktails are great - I had Sex On The Beach every night [I wish]. Yammas.
My mate & I stayed here for 1 week, and overall the Filoxenia is a good hotel. The location is only 10-15 mins walk into the town, the poolside bar is great for relaxing and does good snack foods. The staff are friendly and helpful. Just one issue: on two occasions, we returned to our room at the end of the day to find the cleaners hadn't locked our door [on one occasion, the door was left wide open]. Luckily nothing was stolen, but could well have been. Other than that though, I would recommend this hotel.
