We are a group of seven friends travelling to Athens for the Marathon and stayed in Konstantinos Place for 5 nights. His brother welcomed us on the first day and showed us the apartment and sightseeing options. He was super helpful and nice. The apartment in general is nice for seven people and we were having breakfast and once dinner all together without any issues. The location is ideal for checking out the area and it's really close to the marathon finish. Also its a max 10 min wallk to Akropolis and and other very nice areas in the city. On the streets we were easily able to find parking spots for our rental cars, so all in all it was a very nice stay and we all would recommend stayind there.
A final plus is the amazing view from the balcony!
Thanks & see you!
