Great apartment! Lots of modern appointments, very comfortable, convenient location near the flower market (and a supermarket, restaurants, bars, trams, almost anything). Our host was very helpful upon our arrival then got out of our way (we don't need a lot of hand-holding during our travels).
A note of realism that is in no way a criticism. Regarding the "sleeps 4" description: We took this apartment thinking our son might join us.. He didn't so we had the place to ourselves. We're rather glad things turned out that way. There is a bedroom with a king size bed (and spacious closets), plus a living room with two sofas (each could comfortably do as a bed). If you're planning on using the living room as a sleeping room it will be crowded. I suppose one should expect that. For a couple this apartment is a worthwhile splurge. We had an excellent experience in Amsterdam and having the right place is definitely important. I highly recommend this apartment.
