One word: Amazing!
From the check-in to check-out, everything was perfect! The house is located in a very nice part of Lisbon, very close to many bars, restaurants (it literally has one of the best cocktail bars in town next corner). Zoriana was very attentive and resolved any need I've had during my stay from an early check-in, even to lending me her book which I got into after finding it in the house! The house also partially gets the sunset so the balcony becomes very enjoyable!
If you're coming for a remote working, the house has a great internet connection and a working desk. The only part was that there was some heavy construction happening on the streets closeby, and next to the building. However, that also seemed like more closer to being over than just starting, so I wouldn't worry about it that much. Even out of the 4 nights I stayed, there was only noise for 2 days!
Don't miss this gem in Lisbon!
