The unit is in a great location and the street was very minimal and we felt safe. However, there is room for improvement. The shower had mold on the edges and there was no appearance of attempting to remove/clean it. Also, the host reached our several times before the trip to request passport information via an app, which felt sketchy and did not work. Several emails were asking about our arrival time. Another email was to offer transportation from the airport for 30 euros. We decided against their offer because we realized in Lisbon that companies are price gauging Americans and we were right. In Porto, we took an Uber from the airport to the Airbnb and it was only 13 euros. Lastly, the air conditioner is programmed to eco mode, which is fine, however, when we would turn it down to the limit allowed, it would only cool for an hour and it would return to 30 degrees Celsius, which resulted in us having to wake up every hour to turn it down because it was hot. We traveled during a particularly hot season.
