Pros: Clean, centrally located, comfortable, and very spacious. Easy to find, easy to get in and out, very convenient.
Cons: Slightly tacky decor; located in a very tourist-y part of town (think: big chain brand shops, overly-priced restaurants, and street vendors selling tatty toys that spin up into the air). That being said, Lisbon is quite easy to get around, so it's not long until you're in more trendy/interesting parts of town.
Overall, I would recommend this airbnb - it's a decent price, centrally located, and matches description.
