Great location, very confortable flat, plenty of room for 4 guests (6 with 2 in the living room will work fine too, but only one bathroom), confortable beds, kitchen well equipped, efficient wifi, nicely decorated.
Very steep and long stairs to reach the flat.
Not very well insulated in term of noise coming from the flat above.
So nice to have a code to get in the flat, so no keys to share / loose.
Very accommodating host regarding check-in and check out.
