Hey Gary, thank you for your feedback. You've had the bad fortune to stay in Lisbon during the worst heat wave in history, with temperatures over 45 degrees. As you can see from other reviews, guests have no complaints about the heat. as the flat has no aircon but a very good airflow, with windows on both sides of the flat - with the draft, it's easy to cool the flat down during the hot days. Also, there's a fan though we usually don't use it. As per rough sleepers, it's been a growing problem in Lisbon. It's worth noticing though that Lisbon remains one of the safest European capitals.
