Thanks for your feedback. Regarding mentioned points, we would like to clarify that to this day, we never had anything like this happening in Antiquarium, nor any complain regarding security issues!
Of course if any guest don't comply with normal and universal standard rules, like not locking the main door, or leaving windows open while they leave the building, unwanted scenarios may happen.
Due to the dubious nature of this event, since it only disappeared a specific object when there were other more at disposal (e.g.: iPad, mobile phone, etc.) and there were no signs of a forced entering at the building, it’s almost impossible to decode the homogeneity and suitability of the facts.
As other guests have mentioned, we are located right in the center of Porto, in a very comfortable house, in a great location and very close to the main historical and city attractions, and by the date no one complained about any problem regarding the area or location!
We have appreciated your visit and frankly regret to hear that your experience was not as expected!
