I recommend Teo's place because it is good value and very well located.
Be aware that you are sharing a small apartment with Teo and his girlfriend. if you just need a place to sleep, it will work out fine.
Teo waited for me to arrive before he went out, which was really good.
He answered questions when asked, but he didn't offer any suggestions about what to do or see in Athens. He was polite but not particularly inviting.
Definitely good value in a good location.
