Cozy apartment, great location, comfortable bed. Antonio's place has a great location, and is a 5-10 min walk from restaurants, markets (also a Chinese market a 5 min walk away) and some tourist attractions. Baixa and Alfama were ~15 min walking. I took an uber from the airport, and was only 7.50 Euros. Check-in was easy -- there was a keypad for the main building door and a key for the apartment. Easy to communicate with Antonio and he was very responsive. As a solo traveler, the place was perfect for my needs. When you walk into the apartment, there is a small kitchen with a mini-fridge, a table to eat that seats 2, and a bathroom (shower was small, but the water pressure was great. I loved that you could adjust the temperature and pressure). You go down 3 stairs and there's a couch, tv and a large bed. The bed and pillows were quite comfortable. Great view, and you can see a glimpse of the castle. Also, I loved that the area was QUIET. Lisbon can get quite loud at night, but this area was quiet, and I was able to sleep with the windows open and still get my beauty rest. Do note the walls are a bit thin, so I could hear my neighbors come in and out (and hear them arguing) The apartment had basic amenities so that you can cook simple meals at home as well. There was salt and sugar, but wish it had a few more items such as olive oil, vinegar.
Antonio was an AMAZING host. I unfortunately fell and sprained my ankle on day 3 of my trip, and Antonio went above and beyond. He offered to take me to the hospital (luckily it wasn't needed) and arranged for the cleaning lady to help carry my suitcase down the stairs during my departure. It was a scary experience being hurt in a foreign country, but Antonio was there to help which was so comforting. I'll never forget the kindness he showed me.
A couple things to note -- the apartment is a little small, perfect for 1 person, but I think for 2 people, any stay longer then a few days might feel a little crammed (especially if you're coming from the US and use to large spaces). There are 2 flights of stairs you need to take to get to the apartment -- easy for the non-injured, but something to note. Also, it's located on a hill, so you have to climb up or down to get around by foot. Both stairs and hills are really common in Lisbon, but thought I'd mention it because I didn't know that prior to my arrival in Lisbon. Overall, I really enjoyed my stay at Antonio's!
