The lemon tree house is absolutely stunning! It is sparkling clean, well stocked for cooking, has a very comfortable bed, and an awesome garden to sit in when the sun is out and have a swing on the hammock. Ermelinda was a very warm host and welcomed us at the apartment with her lovely family, and was very quick to respond when emailed. She kindly left us some fruit, nuts and local port wine which she informed us was vegan when we mentioned this. Very helpful maps and books left out about the area of Porto, this place is a 5 minute walk to the train station with easy access to the centre of Porto, and surrounded by restaurants and shops down little streets to explore. One of the best places and great value for money I have stayed in through air bnb, and we will definitely be back. Many thanks Ermelinda :-)
