Overall, we had a good stay for the price we paid. However, we feel there are a few things to improve.
There were a few things missing in the house. The kitchen didn't have any pan available for cooking. There was only one dishwasher capsule was provided and very few toilet paper rolls (3) were available for a full week.
Very low flexibility from the owners (The Porto Concierge).
The house was extremely cold during these winter times and the existing electrical heaters (in the house) were not strong enough. We've asked for an extra heater to solve this problem and they answered quite fast that they would check and let us know. In the end, we didn't get any further response and we got this cold for the whole week. On the check-out, we've also asked if we could leave one hour later due to transport limitations on covid times but they were not flexible at all (and they had no booking after us).
