Gustavo's guest house was a perfect stay for our overnight in Chula Vista. My boyfriend and I had plenty of privacy and Gustavo and his wife were very welcoming upon arrival. The kitchen was perfect for making a quick snack and the mattress provided and AMAZING night's sleep (seriously, good luck getting out of bed in the morning).
I would recommend Gustavo's place to anyone looking for a more personalized and comfortable place to crash than a hotel.
