This is one of the loveliest Airbnb's that I have ever staid in and the location is just perfect! Goncalo, the host, is super nice and great about communicating and answering questions, and there is a whole binder full of tips in the apartment, which is very useful. The apartment itself is very spacious, clean, and well appointed for long stays with everything that you might need, and the view from the third floor is simply gorgeous! It is an excellent place for both short and extended stays and the place itself is even better than the photos. The beds are comfortable (firm) to sleep on and the decor is aesthetically minimal and tasteful. The heating/AC and the washer work great. The wifi is also very good, I was able to do all my work video calls with no problems while co-working with another person who was also using the wifi. There is a huge table in the living room that seats 6 people for eating and working and the living room has lots of natural daylight. There is also enough space in the living room to do yoga, which was a big plus for me, especially during Covid times. The kitchen equipment is a little dated but works well and the bathroom has a spacious shower with a great rooftop view. The Principe Real location itself is ideal - you are in a beautiful, quiet area that is only 5 mins away from all the Bairro Alto action (with all the tourist bars and restaurants) on the one hand and the super posh Avenue de Libertad area 5 minutes away on the other hand (you can go jogging around the long tree-lined avenue). The Principe Real area itself is very pretty and trendy, with lots of great eating, shopping and amenities options. If you like to go out to eat for breakfast, lunch and dinner, you will be very happy here. My personal favorites were the Instant Crunch and Seagull Method cafes, and the Corallo coffee shop for lattes and amazing chocolate (turns out that the founder, Claudio Corallo, is a world famous chocolatier, so make sure to go there.) The castle and Alfama are an easy 15-20 min walk. There are lots of options for small supermarkets/pharmacies/small shops, there are regular markets in the garden square that's right next to the place, including a farmers market on Saturdays, and the large El Corte Ingles supermarket with everything you would ever want (including the Eric Kayser French bakery) is a cheap 10 minute Uber ride away. I was so happy in this place that I extended my stay and when I come back to Lisbon in the future, it will be my top choice place to stay! One general comment to make about Lisbon - the whole town is very hilly and most of the historical apt buildings have very steep narrow staircases with no elevators, which is also the case here. So if you have any kind of mobility issues, you might want to take this into consideration, because the apt is on the third floor.
