There can be reasons why no one could guide you for guest houses in lahore... firstly majority people have someone they know who lives in lahore... relatives or close friend.. so all the outsiders stay at their homes whenever they are in lahore.... and they do not know much about lahore guest houses
secondly some members might have answered these questions so many times in the forum that at a certain point it gets tiring to say the same things over and over again!
All i can say for you my friend you made a decision on your own.. which was a great step.. call it bad luck or bad timing.. just do not let this effect your future plans to visit lahore or anyother place in pakistan! nothing is 100% perfect in pakistan
you have gained experience from this.. now you will be able to tell much better way which is a good place to stay and which is not!
