This is a very comfortable, clean & well-maintained apartment in Porto.
We met the owners on arriving so that they could provide us with keys and they were very helpful during our check-in; outlining where things were in the unit and recommendations for dining, shopping, etc.
The unit is on the 1st floor above ground level. There is an elevator but it is TINY. I used it only to take our luggage up & down upon arrival & checkout; stairs at all other times.
Parking can be a challenge if you rent a car both in finding a spot on the street & getting into said spot (very STEEP hill!) but if you parallel park at home, shouldn't be too difficult.
The location is great. When you get to the street, go right and up the hill to a main street where there are some great cafés and padarias. Continuing up that street leads to the Rua de Santa Catarina for its outdoor, pedestrian mall and shopping. Go to the left from the door and you head down the hill towards the Sé and all of downtown Porto. The only drawbacks are that there are homeless people camping out in doorways nearby and, as night settles, some potentially undesirable characters emerge.
The unit has everything you need re: kitchen appliances, etc. The bed is comfortable but the pillows aren't. Thin & don't support at all. Hot water was great until our last day when, either by accident or design, it turned off in the morning. Could use a few more towels, too.
Overall, a great experience & would recommend this unit.
