You'd be surprised.
Think "floating house with all mod cons" NOT "boat". Compared to many HK apartments which are poor quality construction, terrible for noise, rooms all much too small and kitchens which are quite appalling quality (no oven, for example), the boats here have large spaces and high quality fittings, mains power and water (so normal kitchens and bathrooms) and they never actually GO anywhere.
On your budget, most of my criticisms of apartments can probably be mitigated, but you might want to leave your prejudices at the door and take a look.
There is no way in the world I would have considered living in a boat before. No way. Hated the things. But I love this one - mainly because I wanted a bedroom that had enough room to walk all around the bed, PLUS large wardrobes, PLUS a nice big set of drawers and a dressing table, PLUS an en-suite bathroom with room for amenities as well as the minimums..... And i wanted a kitchen with a full size oven, dish-washer, full size American fridge-freezer with icemaker, room for a couple of microwaves and cooking surfaces - all of which I have here and which I didn't see in any of the flats I looked at. Having said that, I refused to look at flats over 30k a month (4 years ago) so not in your league.
And I didn't want adjoining walls with neighbours making noise at all hours of the day and night (a huge problem here).
Anyway - each to their own. Its a suggestion.
