Constantinos’ apartment is really sunny, beautiful and comfortable. It is located in the city center, all attractions are within walking distance - we visited all of Athens without using public transport!
The flat is modern and nicely decorated. Everything is perfectly clean and tidy. The apartment is provided with fresh towels, shampoo, soap, hair dryer, TV, fridge and basic things to prepare meals.
Constantinos turned out to be an extremely helpful smiling man, he answered all questions very quickly.
The only downside may be the district where the apartment is located - we did not feel safe returning to the apartment in the evenings. However, the district seems calm during the day.
Although the apartment is located on the seventh floor, the street sounds are very loud. Light sleepers may need earplugs (Constantinos has taken care of such). There must also be a music club near the apartment, because on Saturday we heard loud music all night long.
