We have rented Margarida’s apartment for 1 month, and that was definitely right choice. It is cozy and good designed with a lot of small pretty details, art albums on bookshelves, wooden furniture, beautiful plates and dishes. It has a huge sunny terrace, fully equipped kitchen, 2 bathrooms, nice living room – it will perfectly fit a small group both for long and short stay. It has everything for comfort living.
It’s situated in calm area, 20 minutes walkling from Torre dos Clérigos. There is a big supermarket and some local restaurants in the area as well. Wi-fi is good, heaters are hot 
Margarida met us in apartment herself, she is a very nice person. She was very helpful, answering all our questions. She was always in touch with us, so we felt care. We highly recommend Margarida’s place to stay in Porto and to have good time there.
