The location is ok, quite central, but definitely not the best area in Athens.
It looks quite dodgy, especially at night.
As I landed in Athens at 2am, I asked the host to accommodate for an early check-in - Unfortunately my request was not accommodated and I was asked to wait outside the building until 3pm - Supposedly for the “cleaning team” to finish. I did not see any cleaning team leave the building as I stood outside in the heat for 40 minutes.
The place is apparently clean but there were cockroaches in the kitchen and bathroom (they came out at night!) so I did not use the kitchen as I found it really disgusting.
The bed was assembled incorrectly, so the wooden boards underneath the mattress collapsed under the weight and it felt quite unstable. I was scared the whole bed would collapse in the middle of the night as I was asleep.
The host offered to send a handyman, or a “technician” to have a look at it, but I did not want anyone in the flat where I left my passport, iPad, documents, money. Especially I did not want anyone to touch the bedding while I was gone.
The towels in the bathroom smelled and the armchairs in the bedroom looked filthy.
Overall the flat is in a central location and at a reasonable price, but I think there are much better places in Athens.
I would not recommend.
