Quinta do Gestal is a wonderful and restfull place to stay.
Alvaro and Rosa, the hosts are also super nice so our stay there (even one night) was great!
Just one "drawback", Quinta do Gestal doesn't have a number of street, but you may check this name directly on google maps and it will be all fine (there are some signs on the streets tho)!
If you are looking for peace, do not hesitate to go there!!
