The duplex is incredibly clean - we briefly met the cleaner and despite nether of us sharing a language, she was very warm and welcoming and showed us around clearly showing us the amenities.
It is around 15mins walk to two Metro stations. Lots of different types of bars, cafes, restaurants. It's worth noting that you need to get the metro to the beach (which is simple enough).
The duplex is at basement level, which I hadn't expected because of being called a loft - but that was my misunderstanding.
If you want to cook it is a very well equipped kitchen; and a nice space to be in.
Through no fault of anybody we visited during construction work on a nearby building ; and general sound from other people's apartments can be heard quite loudly.
Leslie was very easy to contact, and replied to messages in a timely manner. A very kind and warm host.
