This flat is all about location. A few metres east of Monastiraki square, it could not be more convenient for transport, with two metro lines crossing at Monastiraki, and with the Roman Agora and Hadrians Library within 2 minutes walk (and both easily visible from the balcony of the flat) and the Greek Agora (with the Stoa and Temple of Hephaistos) within 5 minutes walk. A restaurant (O Thanasis) selling large portions if Greek food, very cheaply, is a few metres away. The view from the balcony of the Acropolis, which is floodlit at night, is something that alone is almost worth the cost of the flat!
Very good host who met us at the metro station before taking us the very short distance to the flat. The flat was very well equipped.
Of course, being in the centre of a busty part of a busy city carries with it inevitable consequences. Although on the 6th floor the noise is noticeable, particularly on Friday and Saturday nights. Nothing more than you would find in a similar position in any busy city, but if you are a very light sleeper, take some good earplugs.
Take care on the underground – pickpockets abound. Take care with the taxis. They will try and cover up the meter and then invent a price, and do not always know where they are going. Keep Google maps open on your phone to make sure you are where you want to be before getting out of the car.
