Walking, it takes at least 30 min to get to the tourist areas and around 15 min to get to the closest hop on hop of tour bus station. It is a little bit noisy in front of the building but still I consider excellent value for money.
Andreas was very helpful and the flat is spacious and very nicely furnished. I like to think that living in his home gave me a feel on how everyday Athenian live inside the city which added to my entire experience.
