The hotel is clean and comfortable, the breakfast is ok and you get free internet in the lobby. Reception staff is very helpful and friendly. A great advantage is that you can walk to the places of interest you might want to visit. The Acropolis for example is about 15 minutes away. Good value for money.

Be warned PLEASE, Omonia area not safe at night, confirmed by Police and Airport staff, BUT no one warned us (not even the Hotel receptionist when I asked where to go and eat in the evening) And I was not happy with that.
SO LESSON learnt, IF it's cheap there must be a reason !!!!!!

Stayed here based on a very cheap price (€27 for a twin room) with low expectations! Room was very clean, with towels replaced daily. Staff were helpful and tourist attractions were a 10-15 minute walk away. Free wifi and a big sunny balcony were a bonus. Only downsides were dusty balcony furniture and noise from other guests through very thin doors. As an extra tip, try the kebab shop 200yds south at the traffic junction - excellent chicken souvlaki for €2

For 35 EUR per night, this place was much better than I had expected: the room was quite clean (including under the beds), included a working fridge, ok breakfast (cereal, lunchmeats, nutella, coffee, tea), and free wireless. Downsides: wireless was not reliable and the area really is dodgy -- the red-light district is only a few blocks away and there are lots of groups of men loitering on Acharnon Street; very few women on the street or in nearby cafes after dark. My sis and I are both accustomed to urban blight and knew what to expect and to cope with the conditions, but definitely not an area for corporate or people with kids. (Also, there were times the wifi got real poky or cut out -- not a big deal but better not to try telecommuting from there.) Bathroom is indeed small -- you will get the whole floor wet when you shower -- but that's typical of urban budget hotels, in my experience. Staff was quite friendly and helpful overall - there was one tense exchange that could be attributed to language barrier + unusual situation (the clerk was very uneasy about discarding a phone message that had been left for me [I'd resolved the issue via e-mail before he relayed the message], trying to insist that I come fetch the number]), but they handled our other requests just fine (ordering a taxi for the airport, providing a wake-up call, and mailing our postcards). Soap is provided but not shampoo, but there's a decent bodega down the block. The Acropolis and Plaka are 15-30 minutes away by foot depending on how fast you walk -- we didn't take the Metro at all while in Athens. (The receptionist looked at us askance at our plan to walk the whole way, and Wikitravel will tell you that tourists have no business being on Acharnon or 3 September St., but we would have missed the wonderful Central Market on Athinas Street if we hadn't been hoofing it.)
