First and foremost, the Pangrati neighborhood is ideal if you want to walk to all major Athens monuments and avoid public buses or taxis for the most part. Note, Pangrati is not a flat neighborhood and the apartment is up on a small rolling hill. It's around a 30 min. walk to the Acropolis. If you opt to cut through the bottom of the National Garden next to the Zappeio Hall, the white paths you see on Google maps are actually wide, paved streets where no cars are allowed. The park has fresh air, a green parrot colony that flies around, and lots of manicured orange trees. Cutting through the park puts you in the direction of the Acropolis and Syntagma/touristic shopping areas with winding streets. Be very careful when crossing streets in downtown Athens. I stepped out into a crosswalk next to a park with a red light for cars, and a rogue car blew through the crosswalk speeding, missing me by 1 foot. Four people around me gasped in horror. In that moment, I regretted that on this trip I didn't have travel insurance to cover medical care if I had been hit.
The apartment itself reminds me of pre-war apartments in NYC due to the high ceilings and marble and wood herringbone tiled floors. Very classical aesthetic. The living room, both bedrooms, and the kitchen all have a set of glass doors that lead to the exterior balcony, which means nice light in those rooms. In winter, the radiators are connected to a central boiler and radiate heat all day if you want. The building has a reliable 2-person elevator, although, for some reason, the internal doors to it did not close whenever I used it, so you had to be careful. The building corridors do smell intensely of cigarette smoke, which gets sucks into the apartment near the front door and into the bathroom intermittently. The outside balcony is great, but could use a nice sofa set for lounging on the southern side that gets full sun. Note, the apartment is on the 4th floor, thus many other surrounding apartments that are on the 5th - 8th floor look down on your balcony (i.e. not as private as if you are the highest balcony with nobody looking down on you, which I had in 2 other rentals). The kitchen has generous breakfast food provisions, but no instructions were left for how to use the stove. Note, there is an electric switchboard in the hallway around the corner, and you have to flip the switch for the kitchen in order for the electric stove to work. Likewise, there is a clothes washing machine in the bathroom in Greek, but no instructions are there for easy use. You have to plug it in, turn the metal water valve on, and direct the tube for the exiting water to the toilet bowl with the toilet lid closed. I loaded the washer, hit the main power button, turned the dial to letter 'A', and it would do a cycle in an hour or so. The dial indicates alphabetical order with 'A' being the beginning of the longest possible wash cycle. No detergent was there, but I travel with my own that I use. The shower has a half-glass wall, thus a lot of water can splash onto the floor when showering if you are not really careful. As 1 person, I was given 1 towel, 1 handtowel, and 4 small washclothes. There was no bathmat, so I had to use the hand towel as a bath mat. There is a natural fiber rug in the bathroom, but I don't consider that a bath mat, as it's thick and dries slowly. I recommend 2 large towels per person and getting a designated bath mat (cotton) for the floor. I suspect this rental outsources the laundry/cleaning, so towels are rationed, whereas other rentals provide a closet full of extra linens to access, if you need them (which I really like).
It was suggested that the best supermarket nearby was Sklavenitis, across the Alsos Pagkratiou park (on Google maps), but that park is a steep, rocky, hillside with lots of staircases, which means if you buy a lot of heavy liquids, like bottled water, you have carry them back up the parks' stone staircases to go home. Not ideal. Instead, I recommend the larger "AB"supermarket at Spirou Merkouri 38 (but not open on Sunday). You will walk downhill from the apt. and then up another small hill to reach it. Seems less treacherous than the park. Note, you can drink tap water in Greece, but everyone buys bottled water in 1.5L bottles for around .20 to .50 Euros each.
When checking out, note that the front door to the building is locked after a certain time at night, so if you are leaving late, you could get locked between the apartment and the main front door, which would be horrible. This means you have to take your suitcases to the front lobby, unlock the main front door, and then go back upstairs and leave the keys on the apartment table. This allows you to exit the building after hours. A taxi through the BEAT app to the main Syntagma X95 bus stop at 3 am was 5 Euros and only 5 min. The X95 bus to the airport is 6 Euros and takes less than an hour (it always speeds). You can buy a ticket for the X95 bus at the Syntagma ticket booth using a credit card from a human rep., even at 3 am.
