We had our stay cancelled by previous host (in a different area) 4 days before our trip and we couldn't be happier (I must thank the previous host) otherwise we wouldn't have met this fantastic place owned by Vasileios.
The apartment (like a loft) is just as the advertisement and pictures. In fact, to be fare, it's much better. Two amazing bedrooms (one downstairs and on upstairs) two bathrooms and a toilet, a big living room and a nice "American kitchen" with all you could possibly need. The apartment is nicely decorated, warn, comfy and clean.
We are a family of 4 and it was just perfect for us. Initially we thought about renting the 3 bedroom but I must say the 2 bedroom was just the perfect size.
Vasileios was a gentleman and was available 24h (as himself made it very clear) for any needs. Gave us nice tips about the area, restaurants, shops, PCR test labs and was ready to help us booking tours and/or tables.
The location is simply perfect. That's the reason for the name "Four Street Athens". You will be in the heart of the touristic Athens in between Ermou and Mitropoleos, Christopoulou and Kapnikareas.
AB Supermarket, The Bakers in the Hood, Attika Bakery, Cookie Land, Kayak Ice Cream and TGI Fridays are just pretty much under the apartment at the same block. Plus you would have endless options for shopping and restaurants around the area all within less then 5 minutes walk. I cannot stress enough how perfect the location is.
You get to the Syntagma square (by the National Garden and Parliament) within 9 minutes in a slow pace via the charming, busy and lively Ermou st with all its branded shops. To the other side you reach Monastiraki square in 3 minutes where you will find some touristic attractions and the Flea Market amongst others.
Plaka neighborhood is a few blocks away and you reach the heart of Plaka in 7 minutes.
Ancient agora around 5 minutes;
Hadrian's Arch within 12/13 minutes;
Acropolis and the Museum also 13/14 minutes.
All in a nice pace with kids and you definitely don't need metro or taxis.
The only site we needed a taxi was for the Lycabethus hill. A 25 minutes walk or 15 by taxi.
(don't use the service of a taxi driver called Konstantinos who will offer a ride to a Flea Market - it's a scam - and he will say he's not charging for the waiting time but will).
"The Greco's Project" in Ermou (2 minutes away) is an amazing place for a quick and cheap local food.
"Shisan Sushi" for an amazing Japanese also within 2 minutes and "LE GRECHE" the BEST ice cream in Greece at 6 minutes walk.
For the BEST night view of Acropolis "CITY ZEN" rooftop just behind the apartment.
In short: this is the place to stay.
