Very nice, simple and cozy Bed&Breakfast.
Super central in Porto's historical city center (nearby Rua Santa Catarina), Aliados, etc.
Clean, comfortable and nicely decorated.
Good communication with Mário, the host.
Great for singles and friends, but maybe not so great for couples, if you want some privacy (no suite with own bathroom), you share the two bathrooms with everybody. But they're clean and super tidy.
