This is a very beautiful room and the owners were so helpful in all communication...really great service. The location in Porto is also very good indeed and we had four AMAZING days in the city (electric bike rides; great dinners; fantastic train trip up Duoro Valley; final day in beautiful Braga).
HOWEVER, our big issue (for us) is that the room was probably too centrally located and we had real street noise issues on two of our four nights (Friday and Saturday). The room we had was on the 1st floor and directly above a cafe and VERY close to the entrance to the metro, and by a busy bus stop. It's a noisy road and you certainly felt a lack of privacy, with curtains drawn during the day. We also had someone ringing on our door at 3am on Friday night from the street below.
SO....if you are a heavy sleeper and are going to stay out late, then this is a great venue. It really is VERY close to the station and all the action. But, if you want your beauty sleep, maybe look further away from the centre and travel in by metro.
Finally, the owners were SUPER NICE when we raised our concerns. They offered us ear plugs and they also said we could move and get a full refund. In the end, we stayed and Sunday and Monday were MUCH quieter....maybe we were unlucky (on Saturday Porto did win a big football match but that doesn't explain the noise on Friday).
Sorry for such a long review but we felt it was important to be constructive and honest.
