Bessie's apartment could not have been located more centrally, so that we could easily visit the main attractions (Akropolis, Temple of Hephaistos) by foot.
Bessie also had an overview with recommendations for getting food. We went to the recommended restaurant for breakfast and it was really good! Check-in and check-out were really easy.
The shower deserves to be mentioned as it is a very cool and modern rain shower. It is necessary to preheat the boiler but that was simple and no effort at all.
Only downside: some other tourists in the building managed to clog the drains because even though it is not allowed in Athens specifically stated almost everywhere they flushed down toilet paper. That meant we did not have water for a few hours one morning but Bessie kept us updated and it was resolved really quickly. So a big plus point for Bessie! :)
