Positives: This apartment is very centrally located within Athens, near the Metro and many of the major sites. It is clean and stylish, and includes a very cute balcony to have a coffee or a glass of wine. Communication with the Athenian Sensations team was faultless, and check in and check out were easy.
Negatives: While the apartment is equipped, it is sparsely equipped - there were only two forks, two knives, etctera, and no basic cooking supplies (salt, pepper, oil, etc). Additionally, the apartment is located right next door to a nightclub which blasts very loud music until it closes at 3 AM. I'm incredibly suprised other reviews did not mention this! We ended up booking a hotel room down the street for our last night so we could get a good night's sleep.
All in all, if you are ok with a basically equipped apartment, and loud noise late at night would not bother you (perhaps if you're out late yourself!), this would be a good rental choice in Athens.
