We have spent a whole month at Isabela’s place in September.
Isabela is a great, communicative, welcoming and outgoing host who is always ready with awesome tips and help.
Her apartment is literally a piece of art situated in a great street in Porto - close to the city centre (5-10 min), yet quite quiet in the night.
There are number of groceries nearby (smaller one at the corner of the street, two bigger ones both 5 min walk).
Trains seem to be the best transport option to go to the beach (Espinho - 30 min from Porto - Campagna) as well as to see some other cities and regions (Lisbon - 3 hours, Guimarães - 1 hour, Braga - 1 hour, wine region of Douro valley - 3 hours). Otherwise, Bolt rides are really cheap (3-7 €) too.
During September, the weather can be itchy (especially during the evenings), so don’t forget to take at least some warm clothes.
For the rest, a bit annoying and loud thing during the day was the building site just across the street. Otherwise, everything was perfect.
