Great place in a very central and convenient location, enough space for probably 15-20 people, ideal to gather a large family or some friends. The landlord was very prompt to answer any question and the house was as described, high ceiling and old style charm.
Place was spotless when we arrived
The challenges were around 1- parking, as very costly in the street, but we were well guided by the landlord for free parking spots ¬20' away on foot, and 2- hot water for showering (not all 12 of us could get a hot shower every day, though we were mindful of saving it for the next family member!).
We had an amazing time, as with young children you can go to the city center on foot, come back for a nap or a meal. The baby foot table in the living room kept all entertained for hours, and the way the house is organized allows for some to rest whilst others play.
We do recommend John's place, and will certainly come back when we need to accomodate such a large group !
