Maria and her Husband were Great. Helped us a lot with the good Restaurants and sightseeing . They also had a take away menu from the local restaurant which was really amazing (because on the day of our arrival evening it was raining heavily and this take away menu saved us and it was really tasty (Try souvlaki). They also gifted us some special drinks (ouzo for my husband and forgot the name of my dink :-) ) which I think is very nice. Overall We had a great stay in Maria's house.
The things Maria could Include is maybe one bottle of Mineral water, Normal Black Tea and Instant Coffee however they had few other options for Tea and Coffee though
