The Casa of José is the right decision if you wanna have a real Porto Casa experience. Let´s start with the location of the Casa: being located about 10 minutes away from the Metro station Lapa (for people with lots of luggage: it goes a bit up-hill, so safe your breathe ^^), the Casa has the perfect location - it´s absolutely quiet and calm, hardly any traffic and no noisy tourists on the street. But on the same hand, it´s only 10 minutes and you have the Metro, or enter the more lively streets that bring you to the center (30 Min walk) or the niceer, not-so-touristy areas (15-20Min walk). A little supermarket is right around the corner of Lapa station, a bigger one about 10 minutes the other direction.
The Casa itself is - big! I stayed there by myself, and almost felt a little lost ^^
You have everything (!), you need, including a waffle iron, a freezer, magazines in the livingroom, hairdryers, a huge TV, a dining room...There´s nothing to miss, I think. WLAN works fine as well.
Super nice asset: the beds. They are big, with good matttrasses and good bedding, there are bedside lamps (important for bookworms ^^) and shutters (for light sleepers).
I think the flat is especially perfect for the hot summer time since it´s a fairly cool place: the floors are tiled - which makes it a bit chilly, and those who prefer very warm places should maybe bring a pair of woolen socks or slippers to wear. But, as I said, especially for hot summers - awesome!
A special feature comes with José and his wife, two absolutely lovely, kind and hearty people who welcome their guests with wine and juice, fruits and pastries. Their warm way of showing you around, offering their help, but, at the same time, keep a polite distance, makes staying at their Casa a fully pleasant experience. 5 out of 5, for sure!
