Blue House were very professional and welcoming. They asked for my flight details and sent me well written instructions on how to get to the place from the airport. I was welcomed by a friendly lady who showed the apartment and told me about what to see in the neighbourhood, and she was always in touch throughout the stay. They were very kind to accommodate my late check out since I had an evening flight.
The apartment is very clean, new and is located at one of the coolest spots in Lisbon.
