My friend and I stayed at Jacob's apartment for three nights when we first landed in Europe. The apartment was very clean. We cooked quite a few meals in the kitchen and found all of the utensils and condiments we needed, which was wonderful. The apartment is in a great location - close to everything but not right in the middle of the craziness. Lots of nice bistros in the neighbourhood.
I had some trouble connecting with Jacob leading up to our visit, but when I called, his son was very helpful before and during our visit. The only trouble we had is that we were very jet-lagged and had odd sleeping hours; subsequently, I think us being up late, watching a movie and talking, disturbed our neighbours and we found the apartment noisy with construction and vacuuming in the morning.
I would recommend Jacob's apartment.
