The apartment has pros and cons.
On the plus side, it is well located and walking distance from Milan's main sights. The tram stop is very close to the front door to the complex. It also seems relatively secure and has just enough amenities to make it liveable for a solo traveller. The host responded to my questions promptly.
On the con side, it is very small. If I couple were here, I think they would have struggled. The bathroom in particular is tiny and feels very cramped in the inside with the door closed. The kitchen sink also very small and slightly inconvenient to use. The duvet provided was also too big for the bed, which made it somewhat unwieldy.
For someone on their own like me, this place is ok for a short stay - however, be prepared for it being small!
