I had a great time at Johanna's and Bob's home. They were very friendly and and I felt as if I were at home. Besides, the house is well-situated, close to the main street of San Carlos.
They lent me their bike that was very useful for me and they helped me with everything they could. As it is shown in the pictures, the room was clean and very comfortable. It has its own entrance and a lot of light.
I would 100% recommend to chose Johanna and Bob :). Thank you both!
