During our stay we had some problems with the bathroom and the room was placed in a very noisy street which could disturb the sleep.
Finally, Alexandra told us that she had booked a taxy for us, because we left very early in the morning, but that taxy never came and we had to book another one by ourselves on the spur of the moment.
Despite those thing, she gave us a really good and detailed map to discover Porto and the apartment was very pretty.
