This is ideally located if you want to explore Athens in foot, and also makes a great jumping off point to get down to Piraeus. It's a large space with a tiny kitchen, suitable for breakfast. Shower pressure is good. Bed is comfortable.
Location can be noisy due to being by bars and a bus drop off, ear plugs were a saviour for me, being a nearly old fart now. Saying that it is a nice location and easy to get around to and from and was very safe.
