I never got to meet Alan personally, but he responds quickly to all messages and called me back quickly when I had an issue getting into the building.
The apartment is set up like a mini-hotel or hostel, with a fully-equipped kitchen and a dining area.
The room I stayed in had a bunk bed with a double bed on the bottom and a single bed on top. There was also a coffee table and a large flat-screen TV (more on that later). In terms of space, it was good for one person, and I think if I'd been there with a partner (or child/teenager) coming back at the end of the day after exploring the city, it would be fine, but it would be difficult for more than one or two adults to navigate the floor space at one time. If you are good at coordinating that, though, and looking for a clean, well-equipped space with a wonderful host, then this is an excellent choice.
Alan doesn't allow guests to wear shoes in the apartment, so you don't have to worry about getting muck all over your socks or feet. The place is also cleaned daily (including the bathroom), so unlike some Airbnbs I've stayed at, you won't be scared to brush your teeth, take a shower, make coffee, or eat breakfast. The apartment is also pest- and vermin-free, which is also sometimes a rare commodity in the Airbnb world.
The large flat-screen in the room was a Roku TV, offering Netflix, Amazon Prime, and other shows I didn't check out because I was busy watching the other two.
The only negative experience I had was with some of the other guests who checked in the second to the last night I was there. I came back to an unflushed toilet and dirty towels in the bathroom. When they returned to the apartment so noisily they woke me up (at 3am), they disregarded the no-shoes rule (as they did the duration of their stay) and proceeded to turn on their TV full-blast, preventing me from getting back to sleep until after 7am. And throughout their stay they continued to disregard the rules, leaving dirty towels in the bathroom, hair in the bathtub, empty toilet paper rolls after using the bathroom—plus that TV blaring nearly 24/7 & wet, dirty shoes all over the floor.
In no way do I blame Alan for the other guests being jerks; he did contact them right away to remind them of the rules—but this had no impact on their behavior, so remember that this is the risk you take when you are in a hostel-like setting with the host of-site rather than staying in someone's home or in another situation in which someone is there to to take care of problem guests face-to-face.
