We had a really lovely time staying at this apartment during our visit to Porto. The location couldn't be better, the check-in was very straight forward and they even allowed us to check-in a bit early due to our morning flight. The apartment was sparkling clean, very stylish, with a full kitchen which we used. There was a little issue with hot water initially, but when we told them they sent someone straight away to fix it and we had no further problems with it. The only downside is that there is currently a lot of construction going on at the apartment next door to ours and there is scaffolding up, and it was very noisy during the day. However, given that there are renovations happening on seemingly every street in the centre of Porto just now, I think this is is an issue that all apartments will share. If you're out and about during the day anyway it really shouldn't make much of a difference to your experience. If we had our time again we would still have booked this apartment, it was a really lovely place to base ourselves in Porto. The transfer that they arranged for the airport was also great and worth the money, our driver was waiting for us and was very courteous and professional.
