Search is over, just book this place. It’s clean, it’s well stocked, it’s nice, but it’s biggest asset is its literally perfect location.
First of all - you must stay in the Plaka district. It’s a no-brainer. Stay anywhere else in Athens and you’ll wish you were in Plaka. It’s Plaka or nothing as far as I’m concerned.
Secondly - this place is away from any crazy noise, restaurants, train stations, main roads etc. It’s quiet, it’s safe, it’s walking distance to everything, it’s triple-secure with 3 different codes required to get in.
It’s super-spacious.
Note that there is no wall between living room and bedroom if that matters to you. TV swivels so you can watch it in either.
Careful of towel-warmer. No auto shut off. I actually burned myself on it.
I couldn’t for the life of me figure out if the wash machine was also a dryer. There’s a drying rack provided though. Also a super-hot towel warmer you can hang stuff on to dry, just keep an eye on it.
There’s a tiny elevator or spiral staircase.
They’ll send you instructions and photos of how to get in. Note that the photo they provide of the main door is not exactly as it looks now. The store beside it has changed. I had to ask for help from a shopkeeper to be sure I was at the right place.
I’d recommend this place to anyone.
