We have a Bosendorfer 170 in our front room. It's a model from the 1920s, so has square legs and the music stand is plain compared to many of the ornate options that were available. We've had it 10 years or so, and it had had little restoration work when we got it.

Instruments from that time had ivory keys, and these are easily damaged. Fortunately ours are in good condition, with a couple of obvious yellow marks but other other than they feel and play well. As it came to us, it had some cracks in the soundboard, but these weren't affecting the tone, the strings were old and a little tarnished, and the hammers were somewhat hard, it was great, but it could have been better... So, we spent some money on it, and our piano tech has restrung the instrument, re-crowned the soundboard, shimmed the cracks, and reworked the action to make it more even. The result isn't night and day better, but I think that's mainly because we undertook the work before things got so bad as to impact the playability.

Due to COVID the instrument hasn't been tuned for a year, and it's sounding quite honky tonk at the moment. We've also got a couple of keys that are sticking a little (just not quite returning to centre when released), I imagine the bat pins need a tweak or some lubricant.
Playing wise, i'm a fairly rubbish pianist. My wife is grade 8 though, and our son is rather musical although he isn't interested in grades and stuff like that. The harp in the first picture is his, along with various trumpets and cornets around the house (and a drum kit).
My job involves music though, i write software for signal processing and work for an instrument manufacturer (ROLI) who make controllers and software instruments. I've got a fair number of other synths and controllers dotted around the house. Actually i've got a bunch of older ROLI Seaboard Grand instruments in the loft, along with a DX7 (of course!), Kawai K5000, and a good stack of synth modules.
Oh, the wife also has a digital stage piano, and i've got a clavinova which is on loan to a friend, and we've got an upright piano at her mum's house. So I guess we've got 4 pianos, hopefully that's peak piano, but you never know.
