The apartment is newly renovated and quite spacey, tastefully decorated, and the kitchen is very well equipped. The host, David, is very helpful - he assisted us with finding a free parking space and kindly guided us to his favourite eating places and bars. All in all, we had a very pleasant stay in Porto in this apartment - it is located very centrally, but still sufficiently far away from all the tourist traps.
It can be tricky to navigate the tiny and abrupt one-way streets of Porto - so make sure to choose your route well in advance.
There is wireless internet in the building, but the coverage can be a little weak in the apartment itself every now and then.
