Thank you for a very pleasant stay and a warm welcome. The day before the trip to Porto, the hosts called us at what time we arrived and what was our flight number. How practical it turned out the next day. We transferred in Zurich. Our plane to Porto had a technical problem and we arrived in Porto 3.5 hours later. When I wrote the message to the hosts with the apology that I didn't know yet how much we would arrive later, because the announced delay was constantly changing, they were very accommodating. Thanks to the knowledge of the flight number, they watched when we arrived at the apartment. And on our initiative, after our actual arrival in Porto, they called us and arranged the details. Thank you for a really great service !. Accommodation is very clean and comfortable.
