We have stayed at Stella Pension for the last 4 years or so - going back again in early October. We consider it to be more than excellent. Very small and exceptionally clean - the daily cleaning is fastidious beyond belief. Run by the owners who speak very little English, who are very helpful and friendly but will stand no nonsense (we appreciate that). It is set nicely back from main center of Plakias but only 2 minutes walk to the Beach, Tavernas etc. Very quiet location. Try to book front of hotel - quieter (a not too busy road runs past the back). We love Plakias but Stella is one of the reasons we keep returning. No pool nor any facilities outside, but that for us is an advantage.
