Let's start from the positives: i) location (Isola is a thriving neighborhood and well connected to the rest of the city, ii) size (the apartment is larger than most units and has necessary space for everything, iii) amenities (it has everything you need for your stay, even the less obvious tools - very important if you are planning a longer stay), iv) value for money (I though overall it was great value based on all above).
Moving to the negatives: i) hot water (true hot water in the shower lasts 10 minutes at best, which is not enough for two people showering one after the other. It is very annoying as it creates a lot of discomfort. I believe the boiler is not large/powerful enough), ii) cleanliness (the apartment could have been cleaned better, we found several hairs on the bathroom floor and in general too much dust for a unit that should have just been cleaned + there are stains on the couch and the chairs in the bedroom), iii) cold unit (given the apartment is large it requires good heating. However, heating is provided through splits, so you have to keep them on pretty much the whole time at relatively high temperatures - not a big problem compared with the hot water issue)
