Rui's, appartment is located in a great location for walking access to most of the old town of Porto. The appartement is located in a small back yard development of an original much larger property. The access is via a gate at the street then through a little tunnel under the original house, so the apparment is away from the main street. The back has been developed into circa 12 two level apartments 6 on each side facing each other across a narrow (~3-4m) paved court yard. The living is very close. We found the noise and smoking by some of the other apartment users quiet intrusive. Unfortunately we did not have aircon to isolate our space from the others and yet maintain a comfortable climate inside Rui's appartment. The bedrooms and bathroom were located on the second level up a very narrow return stairway, be careful at night! I other respects Rui's apartment was entiremly adequate.
