The good things: Loris communicated promptly and clearly and provided good instructions. He was also helpfully flexible with our arrival and departure times - thank you! The apartment location is great - we walked everywhere or just walked one block to the tram. The kitchen is well equipped and functional.
The not so good things: The building is an old heritage building and so comes with a few issues: the lift was very temperamental and the doors sometimes wouldn't close (an issue when you are trying to get your luggage upstairs); the shower has accumulated several years of black mould and there is an unpleasant smell of stale food odours that pervades the whole building - including the apartment. There was an attempt to disguise this with fragrant oil diffusers, but it didn't really work. There were also some very noisy neighbours who kept us awake to around 2-3am on a couple of nights.
This has the potential to be a really great place to stay because of its location, but based on our experience we won't be returning, sorry.
