We have just stayed 5 days at Manolis apartment at Perivolos beach.
The location is just a 2 minutes walk to the black beach with lots of restaurants and mini markets - basically all you need. At the beach some of the restaurants will let you use their sun beds if you buy drinks or food by them.
One of the rooms didn’t have an air conditioning, so it was warm sleeping in that room.
The house had WiFi, but it was slow in the evening when everyone was using it - in the mornings it was super!
I was pleasantly surprised that the room was cleaned everyday! The ladies cleaning even helped me do a laundry.
Manolis is extremely fast in replying
If you are looking for a nice beach holiday with easy bus access to cities, I can recommend staying at Manolis
