Thoughts from a first-time visitor to Athens. Pleased w/ location of apartment. Easy access to coffee shops, bakeries restaurants, grocers, even pharmacies if needed. Walk up street to Acropoli station area (lots of outside dining), the museum and Acroplis itself is further up -- walked all the way to Monastiraki Stn. Also walking distance to Syntagma Sq and stops along the way (Plaka; Zeus temple, garden); Kolonaki Sq.
Highly, recommend using laundromat across the street -- washer machine was difficult to use but maybe not an issue for those familiar with the kind of machine. 3 euros to wash and can hang up laundry at the apt (there is a hanging stand). Apt is plenty spacious, we liked the choice of paint colors and pictures; has veranda w/ chairs, large refrigerator and cooking utensils. Nikos was responsive. In case helpful to future traveler, "K" switch for powering kitchen oven; "W" switch for heating up shower water; interesting door locks (2 to 3 spins when locking or unlocking). There is a garbage container (dumpster) outfront for disposing garbage.
Also highly recommend Nikos' offer to provide a driver pickup at the airport. He is a gentleman and has great local knowledge/ideas. :)
Looking forward to a future visit.
