Our stay at Alfred's apartment was fantastic. He was very quick and responsive to our questions. The check-in/check-out were very simple.
If you have any physical restrictions, keep in mind that there are 3 floors to go up (in US terms, that's about 6-7 flights of stairs) but it wasn't an issue for us.
The apartment had a modern clean look. He provided most of what we needed: big shampoo bottles, toothpaste, dishwasher soap, espresso coffee pods... The espresso machine was a nice surprise.
