I bought into the "quiet courtyard" as I am a very light sleeper, but found it in the middle of some noisy renovation works (with single glazed windows and lots of reverberation). This has been torture for a full month (8am onwards Mon-Sat). It seems pretty clear that any guest would have wished to be made aware of this before booking, so I felt like I was fooled.
The flat is otherwise a good place to stay. I only wished there had been some storage space (strictly none left for guests). I had to deal with a clothing moth infection (feeding on some nuts left open, which I took days to spot). The WiFi is not the slowest nor the fastest, and is sometimes unstable. There was lots of scented candles which I ended up isolating as they smelled too strongly. Finally, the bath has no curtain and no shower head holder, which requires some getting used to it. These are small things that might be resolved by the time you read this (ask if you care about them).
