Very nice location and apartment. Just a few tips, the plug in the bathroom doesn't work so to do your hair you will have to pull a chair up to a mirror with no natural light (and the ceiling light was broken when we were there). Depending on time of year you may want to ask them to turn the heating up for you as it gets very cold around April time. Netflix cuts out quite a bit so don't rely on it too much.
The hosts are fantastic and so is their apartment, but be aware that it is 5th floor and the lift is very cramped and can be very temperamental so don't do what we done and arrive early lugging your suitcases up the stairs to find noone their and no keys.
