My wife and I stayed in Isabel’s apartment for one month and had a good time.
The apartment is well renovated, nice and clean. It is within the city - so expect a bit of street noise, if you need to keep the windows open on a hot night.
The apartment is not big, but for a small group coming to explore Porto, it is all good. It is within 20 minutes walking distance from the center of Porto. We also used Uber to get around, which is convenient and inexpensive.
Thanks to Isabel and her daughter for being very welcoming, helpful and responsive. When the refrigerator struggled a bit on a hot day, Isabel took quick action to have it fixed.
A good apartment at a reasonable price – recommended!
