Alex's apartment is nice, clean and in a condo building with many amenities. His checkin process is smooth. My parents lived in the apartment for over two weeks and had a not-nice experience.
Overall, his communication was poor and inexperience with being a host showed.
His HVAC system was broken but he was unwilling to send help to fix it and instead directed us to tips/manuals that were ineffective. The heating in the living room never went above 63 in the day/50s at night—NYC HPD requires min temperatures of 68 in the day/62 at night. This was very hard for people coming on vacation from a tropical climate.
Other small things made their stay even more challenging: there was no toilet paper, not enough cleaning supplies to use, not enough mugs; he advertises a laundry room in the condo but did not provide a key to access it.
