I had a great stay at Walter's apt! He was very communicative and available prior and during check in, and when I arrived I was pleasantly surprised at how beautiful, modern, and spacious his apt is. The pics do not do it justice! It is full of art and books and modern design furniture and fixtures. It was also super clean and well organized, with little details considered.
There is a bit of a walk (10-12mins) for the bus or tram, and longer for the metro (Moscova or Republicca), so if you have suitcases or shopping bags, or if it's late at night, consider WeTaxi.
You won't be disappointed with this place! Every time I came back after an outing I didn't want to leave and go back out! Walter's place felt like home away from home. Grazie mille!
