This apartment is in a really great part of Athens with lots of decent cafes, restaurants and bars just a few minutes away. It's easy to walk to all the central spots and the metro/tram stop is only a few minutes away if you want to use that too. The place was clean, peaceful and nicely decorated. The kitchen was small but well equipped and we enjoyed sitting on the balcony with breakfast.
There were a few small negatives - waiting 25 minutes for the hot water to heat before taking a shower, the bathroom being small (hard to turn around in if you're big!), the unusually noisy aircon and only having one set of keys which makes it hard to go out separately if there's more than one of you. Still a great value stay in a good part of town but worth noting if any of those would be dealbreakers for you!
Many thanks to Nikolaos for great communication and quick responses which helped us have a grea stay in Athens.
