I stayed at Willian's place for three nights, and had a great experience in his home. Willian's home is very clean and tidy, just like the pictures show online. The view is spectacular, his cats are awesome (Titika is so friendly and beautiful), the guests and roommate were super friendly, and he is quite close to one of the main subway stations. I didn't spend much time at the condo, as I was doing tours and busy most of the time I was in Athens. The time I did spend I fully enjoyed. I was so happy to have an Air Conditioned room, as many part of Europe were having a humid heat wave, ugh. Willian is very personable, helpful, and easy to chat with. Ask him about the awesome Greek restaurant down the street from him...soooooooo tasty! I recommend his place to any traveler that heads to Athens.
