This was one of the worst experiences we've had through Airbnb. I realise there's a ton of great reviews for this place so I'm going to try and be as fair as possible, but our time here was the opposite of what others have written.
We were greeted by Augusto warmly, with a glass of wine. From that point on he seemed to take a disliking to us and we spent 5 nights there feeling like everything we did was wrong, as if we were unwelcome and disturbing to him. We came home late on our last night from a festival, which we gave warning about when we booked over 4 months ago and again when we arrived, and were told off for being loud and waking Augusto and the dogs (the dogs bark every time a key goes into the door lock). Augusto again scalded me from down the hall the next morning, calling me a 'motherfucker' for accidentally cracking an egg too loudly. Seriously. If normally quiet people going about having showers and making breakfast at 11am is too much noise for you, maybe reconsider hosting. I wish that was it.
Dogs. There are 4 dogs living in the apartment, which is much too small for so many. They were mostly kept in a tiny room and then restricted to areas of the apartment away from us while we were home, then let out while we were out. As a result the apartment has a strong stench of dog at all times in all areas and a blanket of dog hair over the floors, including the bathroom and kitchen. Augusto tries hard to remedy this, he cleaned at least twice while we were there, but he fails to mask the smell. The kitchen is the worst and had an almost unbearable stink of dog piss. We are dog lovers and don't think we are over reacting, I can't see why others haven't mentioned this. When we attempted to open windows Augusto would close them all.
I've never felt like such an intruder in someone's home and fail to see why Augusto took such a disliking to us so quickly.
On the plus side, the apartment is cool and decorated well, and is in a good location. The room we stayed in was nice and has a nice little balcony. The WiFi was good as well. Also, Lisbon is a really cool city.
