The location of the apartment is great! If you want to be on the Gaia side, which is a little more low-key and quiet, this is perfect. It's just a few minutes walk to the bridge, which you cross and are in the heart of Porto.
Check in and communication with Jorge and Celeste could not have been more pleasant or straightforward.
Indeed, they went out of their way to help us get some books delivered to the apartment from the UK - that was so helpful.
The downside is that the apartment is quite small however and it is on the expensive side. We also had our car broken into in the recommended car park (Miraporto car park), although we had left a bag visible so we should accept some blame. Just be careful to hide everything from view.
