Staying at Nefeli's place has been one of the best vacation experiences I have had. The apartment is located near all the main attractions, it's not crowded like Plaka or Monastiraki, and takes only 10-15 minutes to walk till Acropolis. Also, supermarket is very close and you can buy groceries and toiletries if needed. Nefeli was very responsive and has good tips on places one should check out while in Athens (check that out). Amenities were excellent, one could only wish some hotels would live up to such standards.
Overall, for me this will be the first place I will try to book for my next visit to Athens.
Thank You, Nefeli, for this great experience!
P.S.
If this sounds too good to be true and you really need at least one thing that wasn't purely excellent, than I would say wifi range and connection could have been better, because I lost wifi the moment I stepped into garden, but it is a really small issue. You should be walking the streets of Athens rather than browsing Internet!
