Im original from Puerto Rico and I've been living in the city for about 8 years now. I have a spare room that I use as my office that I can share with those in need of a safe, comfortable and private place to sleep in. It's economical and very convenient.
I the future I see my self retired in the west coast of Puerto Rico and owning a B&B so I think renting my spare room could be good practice. I actually rent a place in Puerto Rico short term too
I have experience with house swapping and (website hidden) in various places of Europe and the u.s. I love the experience of hanging out with friends from different cultures. It's the best way to learn and eat!!
