Viktor's place is FANTASTIC!
I would definitely return back and I highly recommend it. It is right opposite Neos Kosmos Metro st, and the tram that passes very near the flat takes you to Alimos, Glyfada etc. The actual flat is superb: real clean, very nice shower bathroom, spacious, a great bed, great linen bedding and pillows, really warm with excellent air conditioning and I absolutely loved it.
It is also situated very near a superb confectionery shop, a good supermarket, and near good restaurants (I tried a delicious one in Neos Kosmos, real nice!)
The only one thing that needs improving is the lock to get the keys on arrival. I challenge the owners to change that to a digital lock because it was extremely difficult to get the keys. Simply change the lock from analogue to a digital one to make it easier to read and type the numbers.
Top place, top hood, I would definitely return there.
