Aside from being a nice guy who gave us some good pointers upon settling in at our apartment in Victoria, there were a few things about Nikos:
1) He appeared to be sort of disoriented in the beginning... Was late, directed us towards the wrong apartment, picked up his phone while speaking with us. Guy didn't seem super professional. Either that or he's just really busy and tries to over compensate. Still, nice guy though.
2) We went to a restaurant he suggested, and he ended up being there at the same time as us. He immediately told us to put our menus away as he would order for us. We were under the impression that if he was ordering for us, that he would pay for the meal. That's the culture we come from... you order for someone, it's your treat. I don't think Nikos knew we were on a budget if he thought we would pay for a 4 course dinner (or that we needed a 4 course dinner for that matter?). Wallet took a huge hit that night... Unexpected. Didn't help that half the ATMs weren't working in Athens.
3) Nikos kind of failed to share that Victoria is considered a dangerous neighborhood of Athens. We were okay. But you definitely felt the vibe, especially when half the locals you met (including one of the cabbies) kind of made a face at you when you told them you were staying in Victoria. So yea.
4) Nikos, God bless his soul, but I'm not sure if he's ever walked to any of the places that he said were "walking distance" from our apartment. Besides the national archaeological museum, not a whole lot of things to see were within walking distance. We took cabs everywhere as most sights to see were about 4-5 km out. Can't expect to walk that much in +30 degrees Celsius weather.
5) No complaints about the actual apartment. He disclosed everything we needed to know in the ad and in the message he sent us once we booked. He also stuck around for a little bit as we settled in and told us a few things to keep in mind about the place.
Overall it wasn't a bad experience. We had a great time in Athens and Nikos provided a clean space for our stay.
