The location is about 20 min walk to Acropolis or 4€ by taxi from Syntagma.
Everyone in the staff was friendly.
We had a three person room that had two normal beds and a shorter extra bed. I couldn't find any additional pillows in the room. The bath room was nice and clean. I found it strange that the minibar needs a key.
Like many others have told, there are nice views from the roof top bar, it's worth a visit especially after the sunset.
The wifi was fast and it also reconnects automatically.
We had to leave so early that they had made a takeaway breakfast for us. So, no experience of their breakfast. The breakfast bag was a really nice surprise, that was offered when we told that we will leave early.
There are a lot of original Greek restaurants at Olympiou street very close to the hotel.
