This is an apartment in a great location of Porto, although after a few days the concrete-ness really got to us. Sounds bounce off the concrete easily, so footsteps / doors closing could be heard. It being summertime, we had to open all the windows to let the air flow, which also let in mosquitos and flies, as none of the windows had screens. On the plus side, the host is quick to respond to problems, even though we had a bit of a wait checking in. All in all this was a clean and and nice place to say, especially if you are a minimalist, but it is apparent that nobody has ever lived in this apartment -- it's missing personal touches.
