guesthouse vs villa for 4 month stay solo

Good evening Anna. Well, thats highly depends on a quality of a guest house and the amount of money that you are willing to spend. If you are planning to stay for 4 months, i can assume that this time in Bali will be some form of personal retreat for you, a space and time to calm down, be in stilness, think everything over and etc. For these to stay privately in a quiet villa will be the best choice. Let us know if we can help you somehow.
