For me and my boyfriend it was the perfect place to stay.
The location is on the other side of the Douro river but very close to Ponte Luis, so you can still reach the city by foot with little effort (20-30 min). We love walking around and it was a treat to cross the bridge every day. If you don't lik to walk, metro an bus stations are very close by (<5 min), too. There are also a lot of small (<5 min) and bigger supermarkets (<10 min) in walking distance.
The room was small but had everything you needed: a comfortable bed, a desk, a shelve and a small wardrobe. There is a small window with a cute view over the surrounding area and there are two sockets.
Danilo was friendly, made us feel welcome and helped us with some questions.
There is one other rented room in the apartment, there was no problem with the other guests. We could lock our room seperately, no problem what so ever.
I would definitely rent from Danilo again :)
