Sprios & Electra's place was perfect for our trip. It's about a 15 minute safe and pleasant walk to the main downtown area with the Plaka, museums, food, and bars. The view of the acropolis at night from the balcony was worth the whole trip. They were very communicative and helpful for our check-in especially considering we arrived at 1 in the morning and they were on vacation. They offered fresh towels and sheets halfway through our stay.
The only drawbacks we had were the shower area was a little small and there was no bracket for the shower head (we ended up duct taping it up) and the AC doesn't blow directly into the bedroom so it would only get so cold. I wouldn't let either of those keep me from staying again though!
