We had a great time at Tiago's flat and we highly recommend it. The flat was very clean and organized. The kitchen is well equipped, the internet is great, and the shower is marvellous! It also has washing machine which is great if staying longer periods as we did.
The flat is on the main road connecting Saint-Jean, so it can be a bit noisy during the day, but at night is quiet. Plus, the double glazed windows provide a good noise isolation. The good side is that there is bus stop very close by, and it is near local amenities (supermarket, boulangerie, pizzeria). Walking distance from the city centre and the beach.
The communication with Tiago was also excellent, he replied our messages in some minutes, and he was really helpful in everything we needed.
If you are looking a place to stay in Saint-Jean, we highly recommend staying at Tiago's flat and enjoy the lovely city and region.
