I would have loved to have given a 5* review because the apartment deserved it - but the apprehension caused by the failure of the hotel to send key codes for access prior to arrival was not a good start to our holiday. Fortunately, the host responded promptly to my panicked voice call from outside the locked reception in the baking heat and the access issue was resolved quickly via direct WhatsApp connection.
My expectations of the apartment were exceeded. FULLY equipped - all brand new appliances. I wasn't sure from the description if the washing machine was shared or per apartment, but it was built in to the kitchenette units and came in very handy for washing our sweaty clothes after days out in the heat.
We slept really well throughout, with the bedroom being situated at the rear of the apartment away from the ambient street noise. There was no noise heard from adjoining units and the brand new air-con worked brilliantly - even pushed down to 16 degrees!
The huge balcony with solid privacy dividing walls was amazing and exactly as portrayed in the photos. Perfect for unwinding in the evenings or afternoon siestas. I did think that an opportunity was missed with the minimalist balcony furniture but perhaps this is in keeping with clean/uncluttered aesthetic of the hotel.
Transport links are good - Benizelou bus stop will be your friend for the 040 to Athens, and X96 to Airport, with tram stops to get to Piraeus port.
Would stay again and highly recommend!
