We spent a wonderful time in Xenia and Valerian apartment!! The flat it´s cozy, clean, bright and it´s in a perfect location, in 10 minutes it´s possible to reach all the main attractions in Athens (5 min walt to the Acropolis Museum). Xenia and Valerian are super nice, they waited for us the day of arrival (our flight was late) and they give us all the best tips to enjoy the city (restaurants, museums, bars..) and all the info regarding transports. I would definitely suggest anyone who wants to enjoy Athens to stay at Xenia and Valerian place!
