My husband and I stayed just one night at the flat. We were greeted with the bottle of wine waiting in the fridge which we enjoyed after long day in Athens.
The host was very carrying and made sure we got in without issues. Super easy check in and check out. The location is super central and I had a great sleep despite being light sleeper. The palace is as described, clean and newly renovated.
Because of late flight out of Athens, we asked about storing our suitcases for a few hours at the flat and Lucas has accommodated our requests, which we greatly appreciated.
We would definitely stay there and recommend the place to others.
