Joao was a very responsive and accommodating host. He met us at the apartment early the morning of our arrival before check-in, time, so we could drop off our bags and wash up a bit. The rooms are big, clean, and decked out in sleek Ikea-like styles. There is plenty of kitchenware for cooking, the shower works great, wifi was great, and there is a pleasant window view of greenery and some other homes. This would be a great place for a family with kids, since there is a separate room with little twin beds, and it was great for my boyfriend and I -- we had a ton of space. I would definitely recommend this place.

Some location tips:
Just down the hill from the apartment, you pass a little square, and then find another square surrounded with a delicious cafe and (as we didn't notice until our last night) several amazing restaurants. You can also walk within 10-15 minutes to most bars in the Bairrio Alto, to metro stops, and to a wonderful view point. If you take a taxi to the apartment, I recommend that you have them drop you off outside of Museu Nacional de História Natural e da Ciência - Universidade de Lisboa, and just walk down the hill -- a very short walk (a few taxis had trouble finding the street, and the streets are very narrow). On Praca de Principe Real (just up the hill from the apartment), make sure to check out the shops and restaurants at the indoor market.
