This adorable, comfortable apartment is - as other reviewers noted - in one of the more "gritty" neighborhoods of Athens. Native Greeks (i.e. taxi drivers) did indeed "warn" me that the area is "dangerous", but I found it incredibly reasonable, convenient, and fascinatingly ethnically diverse. I just made sure to either be in by dark or have a colleague walk me home if it was late.
The apartment had everything I needed and was a great place to call home for the 2 weeks I spent volunteering at a center for refugee children. Because of the large population of refugees in the area, there are several NGOs working there. If you are interested in volunteering (for a minimum of 2 -6 weeks) , I recommend PILAglobal or Action for Education!
