Super convenient to see the sights, get in and out of Athens (metro or bus) and sample nice restaurants and nightlife.
The hotel is clean, well organised. The rooms are tiny but super comfortable and for a couple of nights in Greece you couldn't beat the location and the view! Our balcony had direct view to the Acropolis. The service was good.
Only problem is that it can be a bit noisy - probably more if you are on the lower floors next to the street.
Breakfast was average so might be better to sit in a nearby cafe.
Good value for money.
