We had a nice stay in the apartment but we're surprised by a couple things on arrival and during our stay. First off, the windows in the bedroom face an inside area and there is a terrace facing your bedroom. This means no fresh air and you can expect to shut your curtains for most of your stay. The balcony was a reason for us to pay a little more than for a very similar apartment, but this terrace receives no sun whatsoever as it is encapsulated on all sides by high walls. If anything it brings a draft into the house through the terrace doors that make it very cold in the apartment. That is also my next point. The apartment is colder than the actual outside temperatre at times. We had some great weather for February (all the way up to 20 degrees), but with 17 degrees outside the inside of the apartment felt freezing.
To my surprise this host refused to give us towels for in the kitchen (which makes doing your dishes rather difficult) and refused to supply us with toilet paper. We had 2 very small (and thin) rolls that were insufficient for the duration of our stay. For short stays I have never been refused toilet paper by an Airbnb host, and I was taken aback by this.
Altogether the apartment does have a great central location and it is very spacious. It is too cold for non-summer stays though and the host are essentially a bit cheap. We had a great time in Porto nonetheless, and I hope future guests get treated a little better by this host because of our feedback. Tip: Stay out late and enjoy this lovely city :)
