We had a lovely stay at Fabricio's place in Porto and I would recommend it to people who like to stay in central downtown. The communication with the host was fantastic! Although the check-in time was communicated through airbnb for 3pm, we were allowed to put in our luggage at 11am and check in at 1pm. Unfortunately Fabricio forgot out towels, but he brought them very quickly after we contacted him (like 20 minutes). The rooms are beautiful and well equipped. There was a coffe machine (which seemed like a bit complicated to use) and a semi-full equipped kitchen (e.g. microwave but no electric kettle). Unfortunately in the kitchen there were some ants. But not tragedy. The (real) beds were very comfortable but the sixth one, which was just like a mattress, was a bit concave, which made it nearly impossible to sleep on it. The centrality of the apartment was helpful for exploring the city. Fabricio was a very helpful host, asked several times if we need something (maybe if I would have said that there is no electric kettle, he would have brought one). I asked him where to do some fitness in a gym and he quickly replied with his favorite sport.
Summaring the experience, it was very nice place to stay with a friendly host and a nice location.
