Very loud, amplified music carries on every night till 4am. Hence it was impossible to get to sleep till after that time for the 9 nights we stayed. It isn't the owners fault. The flat is surrounded by bars, geared towards the young tourist market, with lots of tables outside and very powerful stereo systems. It's not a residential street. I have suggested to the owner that he install triple glazing as the double glazing that exists there is insufficient. It does not block out the noise. Either that or forewarn guests before they book.
