This place was actually nicer than I expected. I highly recommend it.
Location: if you're not familiar with Athens you might be put off at first by the amount of graffiti in the neighborhood, but this is just Athens. The location is just a few blocks from the really touristy areas but it seemed to be mostly locals..but that means the food is better and cheaper. And it is just a quick 10 minute walk to be in the center of everything. The entrance is just a door with Gaia written on it in an otherwise nondescript building so keep a lookout for that.
Facilities: Nice clean lobby, a small elevator. The room was larger than I expected. plenty of room for two people to move about and a balcony to sit on (though there's no particular view). Things seemed recently renovated or at least well maintained. Very nice tiled shower Generally larger and newer and more convenient than the other places I've been staying on my trip. Lots of outlets with USB ports. Attractive wood and marble interior. Very clean.
Staff: Helpful, efficient, and friendly, excellent English. Know the best sandwich shops. My phone wasn't working and they were accommodating in googling information for me.
I would use this hotel again.
