Ana & Mariana were wonderful hosts - great communication, super easy entry and exit. They also provided some fantastic resources with restaurant recommendations, things to do and see in Lisbon, emergency numbers, etc., everything you could possibly need all in neatly organized binders.
What you should know:
LOCATION - the apartment building is very secure and clean. It is in the absolute perfect location in the heart of everything. You just go downstairs and walk out into a ton of great restaurants, bars, shopping, plazas, markets, and incredible views. Just the location justifies the price.
COMFORT: This was by far the most comfortable AirBnB I have ever stayed in while in Europe (and I've stayed in a lot in multiple countries). Quality mattresses, bedding, pillows, towels, etc. We all slept really well here. Large rooms and quite large master bathroom.
FULLY STOCKED: This was the only place we stayed at that was fully stocked with really nice kitchen appliances, coffee, paper towel, trash bags, toilet paper, washer/dryer with laundry detergent and so on. Everything you could ever possibly need - Ana and Mariana thought of it and stocked it already. They really put a lot of thought into ensuring your comfort so you can really enjoy your visit. Well decorated and lots of great books. It can get a bit warm in Lisbon this time of year, but guess what - they have 4 heavy duty stainless steel fans to keep you comfortable.
Only caution I would give is that being in the heart of everything, people like to party well into the morning hours which can be irritating if you have the windows open for fresh air. We simply closed the windows and shutters and put a fan on us. That completely blocks out sound and light. Highly recommend visiting Lisbon and enjoying this lovely apartment.
