Amazing location and nice flat. I would definitely go back for a few more days!
We came with our 1 year old and two things are worth mentioning.
The staircase and entrance door are very narrow, which makes carrying upstairs buggy, car seat and luggage a bit challenging. Nothing crazy though.
Taxis can access the street, Uber can't. So just avoid Uber and use standard taxis which are btw very cheap and good.
