We drove into Athens from the north. We didn't know exactly what time we would arrive, so Stratos said we could just email an hour before we would arrive. Stratos was very responsive by email (I had purchased pre-paid SIM with internet for my phone). He was not able to meet my wife and I for check-in, but his kind assistant was there right on time. This flat was more space than my wife an I needed for our brief stay, but we enjoyed the extremely central location. My wife and I enjoyed coffee and breakfast (croissants/sandwiches) at Everest just around the corner.
