We stayed for a month in November (2 adults + 1 kid (2 years old).
We live in the private house so the appartment was a bit smaller than we expected but in general it was fine.
I think it would be a bit tight for 4 adults for more than a week stay. Hovewer our parents visited us for a week and we managed to live together.
Both bedrooms have twin beds so not very suitable for couples.
Neighbours are friendly and quiet. The area feels safe and it's quiet, with a lot of grocery shops. It's close to the park. It's close enough to walk to the city center as well. The appartment is near the Pacific metro station which has an elevator (accessible).
Also the appartment is in the building with an elevator (most buildings in the city center has stairs only).
The windows in the appartment are not good, they were wet from the inside during cold days with black mold around (it doesn't smell). Probably it's not an issue in warm-hot days. I left my laptop in the backpack near the window and it was wet and broken in the morning.
The kitchen doesn't have a kettle, but it was not a problem. We had to buy all the small stuff for the kitchen like washing gel, sponges, soap etc. We stayed for a month so it was ok to find it in the shops, not sure how the hosts handle a booking for a few days.
The sliding door to the bathroom is a bit hard to move, so we used it only with parents around.
The internet was fast (over 100mbps) and worked all the time without issues. We didn't have issues with electricity as well. Also no problems with water. The sink in the shower is slow but not critical.
Hosts also provived a baby crib, special thanks for that.
