I am fortunate enough to travel often to all sorts of destinations, both for work as well as holidays.
Seldom, however, do I get to stay in places that are as delightful as Ligia's flat. The flat was clean and modern on the inside (with a particularly great smell!), in a interesting contrast to the buildings exterior, which preserves the quintessential Portuguese architecture style.
Just a stone's throw away from the Douro River, I ended up going to most places by foot (getting lost in Porto's old alleys is part of the fun)
Luísa, Ligia's sister, was extremely helpful and knowledgeable, at times going out of her way to make sure I'd get to my appointments as needed (I had to attend a wedding on the outskirts of Porto).
She was also simply a delight to talk to and I ended up leaving Porto with the feeling that I have made more than one good friend.
Can't recommend it enough.
