The appartment is in a nice location. The metro station is 5 mins away and you can get the train into Gamla Stan in 16 mins (door to door) or take a pleasant 30 min stroll.
Alber was very accomodating, allowing us to check in at 1am following a delay to our flight, use his amazing coffee machine and also store our bags in his flat on the day of checkout until we caught our flight later that evening.
Albers flat is definitely good value for money in Stockholm and we would not hesitate in recommending it to others.
