Alex's place is in a really cool part of town, with a nice local bakery, supermarket and bars like Lola, and it's super easy to get around on foot. We felt really safe walking back from the centre at night, although less so on the way back from the central train station (a taxi would have been better). We stayed 7 nights so having a washing machine to use and space to store our stuff was useful. Particularly enjoyed breakfasts on the balcony (get pastries from Thiseo Bakery) each morning. It's a pretty quiet spot for Athens in terms of street noise, and although we heard the upstairs neighbours quite clearly during the day, it didn't stop us sleeping well.
