Ana was very nice and kind in person, but she seemed a bit challenged to fit the expectation I would have for a perfect host. On arrival day, I wrote three messages with the predicted arrival time. We were there exactly at the planned time. But still we had to wait 10 minutes before the front door because she could not receive our messages for technical reasons. After the check-in, Ana accidentally took our key, so that we could not leave the apartment. We then had to meet her at another place to pick up our key. When we contacted her later in the week because it got really hot and there was no sun protection on the balcony one would expect that she would really try to help us to make up for the bad check-in experience. She said, that she tries (?) to get us an umbrella for sun protection. But this never happened. So we had to eat our breakfast inside, because at 10 o'clock the sun was already burning too much.
The appartement is located very central, but unfortunately directly at a very busy street. It gets loud in the morning so you better bring some ear protectors if you want to sleep with open window.
There was a little "ants issue" in the kitchen. We cleaned up immediately after making our meals and did not leave any food on the counter, so it was manageable.
The bed was a bit hard, but this should be healthy as they say.
Bathroom and kitchen appliances were fine. All is very new.
Overall we enjoyed our stay in Porto. It is really a remarkable city! But next time, we probably will choose another host.
