We used the Panorama as a base for sightseeing in Athens as it was a bit cheaper for 5 of us than a hotel. It should have been great as the rooms are well designed and laid out with good facilities and of course the roof top pool. Unfortunately, it was not.
The apartment was filthy with stains on the walls, old food left under the seat cushions, dangerously broken patio furniture and a handrail at the top of the perilous spiral staircase that was so loose and wobbly, it would have given way under the slightest pressure. NOT SAFE FOR KIDS
Arrived at 5pm in mid-August to find that the balcony door had been left open so the apartment was the same temperature as outside ( 40 degrees) and it took until 11pm to be cool enough to sleep.
There was mould all around the shower and half of the crockery and utensils in the kitchen were dirty too.
The pool looked lovely and has a fabulous view of the Acropolis, however the pool area was also filthy and the pool water was really cloudy.
I emailed the hotel about a month before to book transfers to and from the airpot, but even though I had an email confirmation from them, there was no record of the transfer back when we arrived and the receptionist seemed extremely irritated that I asked her to rebook it (even though this is a service that they offer for E100). It is much cheaper to take regular taxi (and less grief).
It's such a pity, because with some deep cleaning, maintenance and attention to detail, this could be a great place.
