We had a great time at Merav's Airbnb. The Airbnb is large (especially the living area), very clean and has a great location. Communication with Merav was smooth (note: you have to pick up the key for the Airbnb elsewhere in Porto beforehand). We were at the Airbnb to work - the WiFi could be a little better in the future that two people can work with it at the same time.
