Check in was a little hectic as it took awhile for Fontini to come to us. We waited outside the apartment for quite some time until she came. Luckily, we didn't feel like the neighbourhood was very unsafe. In the beginning we were alarmed by all the graffiti on the buildings and neighbourhoods but quickly came to learn that graffiti is a normal part of life and on Greek architecture EVERYWHERE. So the graffiti wasn't a sign a neighbourhood was a bad neighbourhood at all. We rented two places of Nestor's. One in Athina and one in Feron. Both apartments were spacious and well air conditioned. We preferred the Athina location because the AC/electricity would auto-turn off every 8 hours. However, the one in Feron would short circuit everytime we turned on the boiler to use the hot water and would auto-turn off every 2 hours (which meant the AC would go with it). During the day it wasn't so bad but at night, one of us would have to wake up to turn the AC/electricity on again otherwise we would boil. The hot water issue was also a pain at Feron, because we would get about a minute or less with the water running and then the electricity would just blow and you'd have to run out of the cold shower to turn on the electricity and try to get the boiler to work again for hot water. The short circuit would happen randomly as well at Feron. When it happened the first time, thankfully Nestor was able to respond/call me and showed us how to work the electric switchboard. The only other con we would say was that they really skimped out on toilet paper. When we arrived at both locations we barely had half a roll left and we were a party at 6. We did message Nestor if he could replenish the toiletries especially the toilet paper but that never happened despite him telling us Fontini came to drop by 1 roll (1 roll for 6 people who were staying 2-3 days!). We never saw that 1 roll materialize. We ended up buying our own package of toilet paper while staying at both his places.
For the price we got these places though, we loved the location, how spacious and perfect it was for our group of 6, convenience of exploring the area and closeness to everything! My sister and I walked from the house to the Monastiraki flea market/Ancient Agora from the house (it was about a 25-30min walk) that really allowed us to explore the city. We uber-ed everywhere from Nestor's apartments when we went out and they were always very cheap (about 3 to 4 euros each way, especially to Giza one of their party districts) due to its central location. Would definitely come back again but we'll make sure we pre-buy toilet paper!
