I enjoyed my stay at Elina's. I think the pictures are pretty accurate in showing that the place is pretty small, but the view is reason enough to stay here. I've had other friends tell me prior to my trip that I needed to make sure to have a drink at the Grand Bretagne hotel for its view. Elina's place is just as high up above the neighboring buildings and a few blocks closer to the Acropolis than the GB!
The private terrace does add space to an otherwise small room, and you WILL want to spend some time there with a bottle of wine just to admire the view. Athens was rainy when I visited, so I especially appreciated that the outdoor seating area is covered and protected from the wind and rain. Elina also added some nice touches that really made me feel welcome!
