We enjoyed Alberobello although it is quite commercialised and so we would recommend just a two-night stay rather than longer. The trulli is very authentic and in a great location in the centre of town up a side street that is very quiet in the day although not in our experience at night when vehicles are driving up and down and banging doors. Note that almost all the pictures are taken from a position in the doorway. For us, the trulli was smaller than we expected and would better suit a couple or a family with one child - note that if you need to use the upstairs bedroom it is up a steep wooden ladder that has no handrails - our 16 year old was alright but found she had to be very careful. Overall though, we would say that the decor is quite dated and due a refurbishment.
