My boyfriend and I went to stay at Linda's appartment for five nights and we absolutely loved it. It's cosy, homely, stylish and clean on the inside and the outside is beautiful both during the day and at night. Make sure to buy some gin and tonic as Linda let's you pick and enjoy the lemons that grow on the tree. The appartment is a 40 mins walk to the river and a 30 min walk to the city center or you can walk 5 mins to the metro and ride 3 stops to the center which is cheap and worked well for us. Linda is a great host, she left personal touches in the appartment such as custard tarts, ice-cream and beer and told us that we could call her about anything during our stay whether it's a restaurant recommendation or how to use something in the appartment. We would thoroughly recommend staying with Linda. The lemon tree house made out trip to Porto and we were very sad to leave!
