The staying was perfect! Great location, brand new apartment, very cozy. The only concern I had was if it was noisy, because I usually have a hard time to sleep, but it isn't noisy at all and I slept very well during the stay. On top of that, Anna, her mother and Klaus made their best effort to help us with information about Porto. Summing up: I absolutely recommend it; undoubtedly one of the best places to enjoy Porto.
