I stayed at the Perianth and another hotel in Plaka during my visit. The Perianth is uniquely located away from busy road traffic but at the centre of a square with a number of dining and bar options nearby. I believe I was at a quiet corner of the floor, so outdoor noise was not a huge concern, and room to room sound insulation was good (I could hear every door close at the other hotel I stayed). The reception and concierge service was personal. I checked in late in the night, and a very kind young gentleman at reception ran over to the restaurant next door to personally place my order. As other reviews have noted, the design is modern and yet very practical. Breakfast was also very good. I really enjoyed my stay and would choose the Perianth again.
