I had a great long stay here.
The apartment was very spacious for one - it would also be pretty spacious if there were 2 or 3 of you. Veronica was super helpful with everything I needed during my stay, from a replacement coffee maker to a hoover! Veronica, family and Cooza the dog are really friendly and welcoming: they showed me round the area when I arrived, invited me to Easter lunch and sent me off with a goodbye dinner, which was very sweet of them. It was a very safe place for a solo traveller. The rooftop is delightful (I think I've easily soaked up a year's worth of vitamin C).
The location is good. It is close to the city centre, with good bus links if you don't fancy walking, and bordering the pretty area of Mets. It is also very easy to access the beach and the mountains for some fresh air (Ymittos is a 5-10 minute cab ride away).
In terms of cons, light sleepers might find Filolaou a bit loud: it is a very busy road. I am not a light sleeper so it didn't really bother me. The flipside of this is that Filolaou is full of shops, selling almost anything you could want. There are also two great fruit & veg markets nearby (on Monday and Friday).
For long stays, it might also be worth noting that the building has been cut off from gas recently (I am sure it is very frustrating for Veronica, family and everyone involved). This just means that until it is reconnected, the gas oven and hob does not work. Veronica provided me with an electric oven and a hot plate, which meant I could cook most things I wanted to. But if you want to do daily, involved cooking, the kitchen may not be ideal for you.
All in all, a lovely place and good value. Thanks, Veronica!
