We really enjoyed staying at Ismini's place in Exarcheia! The flat is super tiny but the roof top terrace really makes up for it, providing extra space to sit and watch the sunset... The kitchen is not really made to cook in but I doubt that we would've cooked anyway, there is so many places to eat and drink around. The bathroom door doesn't close properly, which is a bit annoying but also not a real problem. We slept with the terrace door open and ear plugs - the price you pay if you want to have both fresh air and to stay in the middle of a lively neighbourhood.
Ismini waited for us even though our plane was delayed and we got into her flat 3 hours later than anticipated. She was super helpful with everything and would have been there to answer questions, had we had more.
