Really lovely apartment in a great part of Porto! Very clean and spacious with a lovely little garden (which gets the sun in the daytime). Whilst staying there we did however have a plumbing issue where the toilet flooded the bathroom every time the upstairs airbnb used their shower - which then led to us mopping up sewage water at midnight on two nights of our stay (not quite the vibe you want on holiday!). No one came to look at the problem. There's also a restaurant in the next building which is quite noisy until the early hours.
However, overall the apartment is in a lovely area which feels very safe - and very convenient for getting everywhere!
