It is fairly tall, even for a Syrian. Taller than average but not too tall. So the height increases risk of injuries from falls (if they climb to the roof and monkey bar along). So that's why I put 4" cardboard around the inside bars (attached it with some cable ties) and had deeper bedding. Which raises the substrate level so the cage is lower
It basically gives you about 10" deep substrate then and a lower cage (and doesn't obstruct the door). It does use a lot of substrate doing that, but the more you use, the less often you need to change it - dwarf hamsters pee very little and you can just keep spot cleaning for a long time (if you can actually find the bit they've pee'd on!). It usually becomes clear eventually where they're peeing then you just take a handful or two out and add another handful or two.
Even with the raised substrate I was a little concerned ours could fall onto the ladder or something else (these tiny ones get injured easily with falls). So I also attached a very large fleece hammock to the roof inside. Plus a large egg box hammock next to it - over the lower areas and harder items. This was partly to prevent monkey barring across the roof. What actually happened was, he could get into the egg box hammock from his shelf quite easily and from there to the hammock and actually uses it and gets off at the other side onto the main shelf.
When I get chance I'll add a photo to show you what I mean! Set up needs to be done carefully for them but the main thing is that they can't land on anything hard or sharp - they're fine landing on soft substrate.
The cage you linked is better in that way - the height is good and the bar spacing is good for a dwarf hamster (although I've had no problems with the 9mm bar spacing on the Plaza.
If the hamster is the type to come to the door to want to come out then the small door at the front wouldn't be an issue - but I think it could be very frustrating to always have to take the bars off to put anything in the cage or try to get the hamster out - and the hamster could jump out of the cage instead.
With the large front opening door they do seem to interact better and get used to you being there and feel less enclosed. To be on the safe side I have a couple of large cushions on the floor in front of the cage - as our cage is quite high up on a table - just in case they try and jump out! But none of them have so far! Our syrian used to put his paws on it and have a good look out of the door and come nose to nose with you for a conversation. Our robo did tease me a few times by running at the door but then swerved round and went up the ladder instead!
It's hard to put into words, but when the large door is open it's like they are still in their safe environment and you are not invading it - but they can also interact with you. With a smaller door you might have to stick your hand in to pick them up. With the larger door I put a cube or ball at the edge and they can climb in.
But the lower cage would be a lot easier to set up safely and I'm sure you could put a tube through the front door for them to walk into.
Most of us prefer a large front door because a) your hand isn't coming from the top b) you can get both hands in the cage (eg if you need to use a tube to get the hamster out if they're shy - then you can put a hand over each end and lift it out c) you can take houses and wheels in and out without needing to remove the top bars.
