I can highly recommend to stay at this place if you want to have a nice and cozy place to come back to, after discovering this beautiful city! Not only is the flat and every room in it very clean and decorated with much effort and uniqueness, Agostinha is probably one of the nicest hosts I had! As a real Lisbonita she knows literally everything about this City!
PS: I also recommend listening to Fado in Lisbon (all Night long)
