Telmo was a great host, easy and fast in to communicate with. He took my group out for a great boatride on the river, I really recomend it to any future guests.
The apartment is huge any very suiteble for bigger groups of either friends or families. Porto is a hilly town, if travelling with elderly or disabled people maybe I would consider something more near the river. However taxis are cheap and its hard to beat the the value for money.
