Great apartment for us 8 pensioners, great comms, check in instructions, easy access via key safe, and fast lift to 4th floor. Bedrooms (individually lockable) were large, with high ceilings, aircon, IKEA furnished with plenty of wardrobe space and shelves. The 3 shower room/toilets looked recent refurbishments and were cosy, clean and after 20 mins heating supplied all 8 of us with hot water. Kitchen was well supplied, although the table was a bit tight if we'd decided to eat in, and or socialise, so we utilised the spare bedroom next to kitchen as a break out lounge which worked out fine (we still had another unused bedroom).
Location (as described) look a little bit out of town, but with all 3 Hop-on-hop-off bus stops within 50 metres, as well as the Athens archaeological museum a further 50, we had access to the museum before starting the bus tour. The Quality restaurant in the garden grounds of the museum, was quality in service, food, vista, open walled aircon blowers was a little (£££) expensive, but we went back to use it for our regular end of bus G&T stop, €8 each.
After an evening out in the Plaka district (after bus end time) we made our way back to Syntagma square bus stop/taxi rank to find it impossible to find a cab (ok, old person naivety, should have used an app), so we walked back retracing the return Bus route, which happens to be the shortest. It only took 20 minutes, and although there are beggars around at various points (as in every city) the high visibility riot Police spaced out along the route (guarding the National Treasures?) made it feel far safer than say, Barcelona's Ramblas.
Overall, we were delighted with our choice of accommodation, would use it again, and are happy to give our recommendation.
