I stayed two months in the winter (Aug/Sep) and Silvia's place was perfect. Not much to add to all the previous excellent reviews. The location could not be better. Silvia was helpful and accommodating, and she was very responsive to my texts.
The place is small as noted but it has a fully equipped kitchen and a large dining table to eat or do work. I never felt like I lacked space (to be fair, I came from NYC where all apartments are tiny). The supermarket is 1.5 blocks away and laundry 1 block away. Wifi was fast and never failed.
