I traveled to Athens with 3 other girls. Nelly's apartment is the best choice for 4 travelers. Very cosy and comfortable. There are two bathrooms (which is very important for 4 girls 😃). Everything is clean.
Nelly is very nice, she picked us up near the metro station and took to the apartment. She advised us a lot of great restaurants (Sabbas is the best!).
So the accommodation was very good!
