Amazing from start to finish.
We stayed in the most spectacular location both in terms of access to the major sites of Athens and in terms of the beauty; we had a fantastic time.
It was also a major help when Miltos took some time out to study the map of Athens with us detailing everything that we had to see if we wanted a mind blowing Athens experience. Every single thing he recommended far exceeded expectations and this seems to be something that is consistent in everything about Miltos.
I would highly recommend staying with Miltos if you have the opportunity.
