Maria has a big house with a garden. The location is simply excellent. From the metro, which goes to the center, 5 minutes. Walk to the center half an hour. Nearby there is a supermarket.
The room is clean. For each guest, Maria gives out three towels. The house has a good Wi-Fi. The only negative - a lot of mosquitoes, if you open the window at night. In total there are about 10 rooms in the house, but there are 3 bathrooms, so there were almost no queues. With hot water everything is all right. In the garden or on the balcony you can drink wine or have dinner.
During our vacation Maria we did not see, but she left very detailed recommendations how to get to the house and get to our room.
We really liked Maria and Porto.
