Sink in the bathroom is a bit smallish, but no problem for me, it's clean and modern and it works well, that's more important. They could have more yoghurt (although the nice little classes look nice, and are tasty) at the breakfast buffet, to mix with the cereals, but I'm actually almost sure that they would bring you when you would ask for it.
Actually I liked all! I booked a standard room but was given a superior renovated room at no extra cost! The room is perfect! Spacious with a lovely balcony with nice views. The bathroom is very nice too! The sink is a little smallish, but everything worked properly and the water was always nice and warm. There is wifi on every floor and in the cafe and it works well. I was in a room at the end of the hall, so the signal wasn't very strong but I could always log in, so it was fine! The breakfast is really good for a 2-star hotel! They actually have everything: different kinds of bread, cake, different kinds of cereals, ham-cheese-marmelade, scrambled egg-bacon-sausages, coffee-tea-different kind of juices-milk, and small glasses with yoghurt! The breakfast area is very nice decorated, modern and cosy! Staff is nice and helpful! I can't say anything about the standard rooms. I've stayed in them more than once, the last time around 5 years ago, and in my opinion they were fine (although the renovated ones are much more modern and luxury), but I don't know how they look like now... The location of the hotel is perfect! A nice pedestrian street with lots of cafes and restaurants nearby, very close to metro station Thiseio, and very close to the Acropolis. Actually you could walk anywhere in the centre from the hotel!
