Our time spent at St. George Lycabettus (and Athens for that matter) was very brief. Because of this, we were never able to have a significant experience while we were there. Having said that, there are a few notes regarding this hotel I will mention.
The single biggest perk of the hotel is that it sits upon Mount Lycabettus overlooking Athens. There is an rooftop bar with an open-air terrace providing a panoramic view that includes the glorious Parthenon which lights up at night and watches over the city. Some of the amenities were unable to experience, but are still worth mentioning is a rooftop pool and a spa. Be aware that the Wi-Fi is an additional cost for service in the room. For free browsing, head to the lobby/lounge area downstairs. When making a reservation, consider making your purchase directly on the hotel's website. They will often a package in the Special Offers page that includes tickets to the Parthenon with your room rate. Since this is the main site in Athens, this is a great way to save money.
The hotel is located in the upscale neighborhood of Kolonaki, and there are many trendy dining options within walking distance. However, to reach most of the tourist sites, you will need to take a taxi or the metro system. Athens can be a confusing place to get around, so be sure to plan ahead. Decent hotel options in Athens are not very plentiful compared to other European destinations, so consider St. George Lycabettus for any trip to Athens.
