The apartment is very well-equipped, with good space and AC for those travelling in the summer months to Porto. It is also in a quiet location, which is conveniently very close to a main bus stop that goes in two key directions: downtown and the coast. The buses run about every 10-15 minutes and are a 18-25 minute ride from key sites and locations in Porto. Taxis are also not very expensive to get to key sites.
There is a large supermarket and a small shopping centre with stores, pharmacies, and cafés, so we had everything we needed for our stay within a 5 minute walking distance. There are also a few restaurants nearby, which we did not try, but some were rated very good on google. Mostly, we ate in town (it is recommended to make reservations at highly sought out restaurants a day in advance).
Elsa is an excellent host. She was very helpful answering questions and communicating on time. Check-in was great, as we had not remembered some of the details of the listing location and she, along with her husband José, helped us navigate the difficulty (which was totally our fault, not theirs). They are both lovely.
Overall, we loved Porto and this apartment is highly recommended for a smooth and enjoyable stay, albeit one that requires a quick/easy bus ride into town.
