Apartment: Clean, spacious, great view from the balcony over Porto, modern.
Check-in: Generally the Check in System itself is pretty modern and easy to handle. In our case the Front door was locked, so we couldnt enter the building with the digital check in system. The host was pretty quick to react to our problem and told us the combination for the key box so we could enter the building oldschool with keys. unfortunately that combination was wrong so ultimately a neighbor let us in. not really a great check in experience.
location: well, everything is within walking distance BUT there is a hot-spot for people doing heavy drugs day and night right besides the apartment. so while coming home you always had an uneasy feeling although nothing really happened. you see that hot-spot right from the bedroom window.
