We were a group of 5 young people looking for a cheap place where to spend the night in Athens. We didn't care about comfort and luxury. The only thing we cared about is to have enough space for everyone, hot water and Wi-Fi.
The apartment is old but nice. The kitchen is small but has the basic utilities (I would't recommend it for people who like to cook and experiment); the living room was spacious with a small/old TV (but we really didn't care about that). What impressed us (although for some might seem unimportant) is that there were shampoos and washing gels in the bathroom - it was life-saving because none of us had any shampoo. Great!!
The only thing we didn't like was that the mattresses in one of the bedrooms was too big for the bed, so my friend's legs were a little up during their sleep :D
The host didn't show up but she sent her brother - a very nice, patient and talkative. We loved him!
As a whole I would recommend this apartment for a short-term stay. If you go on a romantic holiday or you are with kids, find something else.
