I am a long-time expat in Costa Rica looking to share my two bedroom house in Curridabat/Lomas de Ayarco with another female or a couple. The house is modern in a nice, safe neighborhood with a guard, has a sunny patio, and cable and wifi internet. It is also quiet. The room is unfurnished and rent is $250 per month, not including utilities.
I am out of the city most of the week so you would have the place mostly to yourself except a few nights per week. This is a great deal if you want a nice, quiet place mostly to yourself but don´t want to assume a lease or set up of services,etc.
