My boyfriend and I stayed for nearly a month at S&S's place, and we thoroughly enjoyed it. For one, we were able to book the place 8 months in advance, which was a huge plus to me because I didn't want to worry about finding lodging closer to the trip. The man who checked us into the apartment who works for S&S gave quick replies through WhatsApp even long before I flew into the country, and was always very helpful whenever I had questions or technical issues.
The apartment is very clean and comfortable, with nice little homey touches, and is walking distance from nearly anything you can think of. The wifi in the apartment is very fast, and access to the pool and sauna was a very nice bonus. For places that are too far to walk, the trams in the area are free and stop very frequently, and the train station is a 3 minute walk from the apartment building--for foreigners like me, all that you need is a Myki account on your phone through Google Pay to quickly go in and out of the train stations or paid tram stops.
The only downsides to the apartment that I noticed during our stay is that on extremely windy days, you will hear neighboring doors or beams creak, which could be unnerving or bothersome for some guests--we did not mind, but the windows were missing their locking pins, so we had issues keeping one of them closed during a particular windy day (if a pin is missing during your stay, just put a screwdriver or pen in the hole by the window's handle to keep it locked). The man who checked us in and the owners now know of this issue, so hopefully they should be properly fixed in time for the next guests, but it's always good to check that you're able to safely lock the window. Also, although the bathroom looks slippery, I never felt unsafe using it, and the owners kindly provided bathroom mats for us.
Overall, I think our choice to stay in this apartment was absolutely worth it, and I hope that the next guests enjoy it just as much as we did.
