It was very nice to stay in the room Dulce. It was not too big, but very light, nicely decorated and absolutely perfectly located. We have got a lot of useful tips from the host. We had nespresso coffee and some tee in the room, which is nice.
We did not use any public transport for Porto, the most destinations were between 5 and 20 minutes walk from home. For Matosinhos (tip from the host) we took the old Train, but there should also be a modern public Transport to reach it.
