We found Hotel Cecil to be a good value for our money. It is indeed on a very busy and not exactly picturesque street, but very conveniently located.
We travelled here with our 12 week old son, and found it quite safe and clean. Our room was large, high ceilings, and a balcony overlooking a side street. I did NOT notice a cigarette odor, and this is VERY important to me. The floors were gleaming hardwood, nothing to hold odors.
The bathroom was small, but clean.
We loved being so close to the market, and having breakfast every morning. It was certainly adequate...cakes, cereal and milk, cheese, meat, rolls, etc.
We would probably stay at the Cecil again, if we were on a tight budget...otherwise, we might like to explore staying in Plaka.
The desk operators were not rude, but not exceptionally friendly, either. They were fine, in my opinion...
