We absolutely loved this hotel and would not hesitate to recommend it. The hotel is beautifully and tastefully decorated throughout. The room was spacious with a separate seating area and had a very comfortable bed with luxurious bed linen. The staff are so friendly and helpful and nothing was too much trouble. The garden area was an additional bonus; a great area for a drink or to make use of the swim in and out pool. Porto is a great city to explore - we can’t wait to return and would definitely return to the GA Palace.
