We had a really good time in Porto. Annas apartment is really nice and very clean, we loved it especially it's location. It's located in a lively part of the city center. A lots of shops, restaurants and bars around. the kitchen is simple, but requires everything need, actually theres no need to cook in Porto anyway ;)
We needed to delay our check In at short notice cause of trouble with our rental car... it was nooo problem at all!!! thank you!
The only thing not satisfying was the WLAN, it didn't work probably! An the cleaning lady stores her stuff in a separate room inside the apartment, which no one told us before, but she only needed to come in once and she rang the bell....
I would come back anytime, when the WLAN is fixed ;)
