Mario was a brilliant host, very thoughtful and very helpful. The house itself is lovely with a great charm (not ideal for those who find it difficult getting up and down of stairs though) - we have a very comfortable stay and the roof terrace was great for relaxing. Even better than the house itself is the location, it is literally 2 minutes walk to the beach, which was so nice! It got a little busier in the afternoon but still not overcrowded at all.
I would highly recommend Monopoli and highly recommend staying at Mario's!
