This is a lovely modern flat in an ideal location in Porto. We found it really easy to explore Porto from this location as it was just on the edge of the old-town and the newer districts. It is very spacious, modern and very clean. The bed was comfortable and large and the flat was tastefully furnished. It is a little bit minimalist and could perhaps do with a cupboard or two in the bedroom but we didn't find this to be a major problem.
In winter this apartment most likely has an Incredible river view but during summer it's actually obscured by some trees... That's not something to complain about but just something to note.
Another something to note is that this apartment is right in the roof of the building as such there isn't much soundproofing between you and the outside world. We'd recommend bringing earplugs as a few times we were woken in the night by seagulls on the rooftop.
We really enjoyed having this apartment as our base for the week though and would happily stay there again.
