during a year I had a piano student in my 4 floors building, and belive me when I tell you that it was pure hell.
he had no respect for the neighbors, he played every day, most of the time until 2am. no one could sleep, it was impossible to rest during the day, to study... everything! and it was always the same music...
for real... I'm now learning how to play, and I bought an electronic, because I suffred so must with that guy, that I couldn't bare to be such an annoyance to my neighbors.
You must ask yourself if you would like to have someone playing a loud instrument over your home every day or not... you will ever know if them will want to hear music at 6am in the morning...
I don't recommend you to buy one, or buy the one for yamaha that you can attach some headphones, but respect the other people.
