We met Irina's husband, Rui and he was really helpful and nice person. The house was very clean and stylish and there was everything what we needed. Irina's Airbnb page is very well written and there's a lot of good restaurant tips etc. The location of the house is good, close to the metro station and Alfama is super cute!
There was only one a bit disruptive thing: noise from upstairs. I guess the Portuguese houses are not that well soundproofed because every morning we woke up to really loud steps from upstairs. I don't think that Irina or Rui could do anything about this but good to know if you are light sleeper.
We were happy to stay here!
