I would highly recommend. i stayed here for just under 2 months - the apartment is newly renovated and had everything i could possibly need.
Catarina is a very attentive host - she'll drop you a message to check up and see if you need anything at all.
The location is great too - far enough from downtown for some peace and quiet but also close enough that you could be there at the drop of a hat.
There's a good selection of cafes, bakeries and supermarkets nearby.
I'd definitely stay here again next time I'm back in Porto.
