Beautiful and immaculate room! The Burgos 21 is a very modern and extremely clean building. No keys needed as entry is by numeric keypads. I stayed in room #2 and it was quiet, spacious and had a very large bathroom and work area with a mini fridge. Definitely a great value. The Kitchen, sitting room and backyard are common space shared by all the guests Burgos 21 is not in the heart of Porto. By bus it's a 15 min ride or 30-35 min on foot. However, Uber is cheap and plentiful if you prefer.
The host is attentive and very friendly. You won't be disappointed :)
