Our stay in Porto was the one of the best places my friend and I stayed in. It was great in terms of the space, decor and the location. Everything was walking distance and pretty central to everywhere we went (15 minute walk, or even less!).
Some complains that I have are: 1. The shower head was extremely uncomfortable. It was not adjustable so it was hard to direct the water directly onto us. It also splashed everywhere as it only aimed at the wall. 2. Also, I found that the floors were not the cleanest when we arrived so it was a little uncomfortable be barefoot. 3. I found that the communication at check in was not very clear. It was hard to reach them through airbnb messenger and through WhatsApp. I had to message them a couple of times. When I got a hold of the right person, I was finally able to communicate with them. I only asked to be checked in 30 minutes earlier and it seemed to be somewhat of an issue for them. We ended up waiting outside for a little while. 4. We also found that the wireless was not the best. In some areas of the apartment it worked well but in most of the apartment, we had little to no connection, especially where our bed was. 5. We hoped there would be a bigger full scale mirror in our place. There was only one mirror in by the sink in our bathroom.
Otherwise, the area was pretty quiet and the space was very nice. The high ceilings made it feel much bigger. We loved the windows to our place and how central it was to everything.
