I absolutely loved staying at Electra Hotel. The location is amazing, in the middle of Ermou street, which is the central shopping street in Downtown Athens. It's a few minutes walk to Monastiraki Flea Market and a couple of metro stations. It's also surrounded by a lot of cafes and restaurants since dining at the hotel is a bit expensive.
The service was great and the hotel was very clean. The rooms and bathroom are ideal for a few nights' stay. Booking was easily done online. Breakfast was basic but adequate and overlooked Acropolis.
We also had dinner at the rooftop restaurant one night and it was a nice fine dining experience with delicious food.
If/When I go back to Athens, I'll definitely consider Electra for another stay.

I have to give special mention to all the staff however in particular to Fofi and Maria at the front desk. Friendly and so accommodating.

We stayed here for a 2 night stay and found it central to everything.

Breakfast was lovely and the view from the restaurant on 10th floor was absolutely stunning.

I would definitely stay here again.

I had booked three nights at the Electra Hotel Athens through my Travel Agent and was required to provide a $100 deposit several months before arriving, along with FULL payment 4 weeks before arrival. On arriving at the hotel, after flying for over 20 hours, I was promptly advised that they had no booking for me, were totally full and were unable to help! When I replied "what am I supposed to do now for accommodation", the Manager promptly put up her hands and said "NOT MY PROBLEM"!!! As a female travelling on my own, this was not reassuring!! I would NEVER recommend this hotel to anyone! The Royal Olympic Hotel Athens, on the other hand, was fantastic - 5 star (as opposed to Electra Hotel 4 stars) and ended up costing me less than the Electra.
