Fantastic stay!
The Tripas-Coração team were extremely responsive, pleasant to communicate with, and easy to reach. They were polite, welcoming, and even managed to help me with a special check in accommodation. The location of the Airbnb is unbeatable, and despite being across the street from the train station and on a main thoroughfare, there was never too much street noise at night to sleep properly. The host laid out many amenities (earplugs, coffee and tea, water, wine) and also personal touches (locally sourced rugs and textiles, a handbook of local walking routes, restaurants, shops to visit, etc.) that I definitely took advantage of. The home itself is extremely pretty with tons of natural light and easy access. What makes this listing so special, however, is the location. Porto is a walkable city and this is just about as central as you can get to easily walk 15 minutes in any direction for every possible sight or restaurant you'd want to visit. I would definitely consider staying again.
