Our stay at Diogo's place was great and well worth the money! Diogo and Patricia were very helpful and quick to respond at all times. I've never seen a cleaner place, and the bed was comfortable. We whole-heartedly recommend the place and the host!
There are three small things I would like to mention, so people can be prepared. These by no means were a problem for us and don't take away from the amazing stay we had at the place. Just something to be aware of.
A proper dish towel would have helped us, but we managed without a problem. Other than that, the kitchen had everything we needed.
The shower has three settings, water from overhead, water from handheld device, and horizontal water from the front! However, the overhead shower (and the ceiling in the bathroom) were not very high. I had to bend my knees a little to fit under the overhead shower, and I'm 5'10 (178 cm). If you're over 6 feet tall, showering could prove somewhat difficult.
The front door opens right into the street, and it's a lively street, especially in the evenings! You will also quite clearly and loudly hear the upstairs neighbours walking around. We weren't overly bothered by all this, but it was noticeable. And Diogo's description of the place includes the phrase "potential for noise", so you can't say you weren't warned.
If you like to be part of the hustle and bustle, especially the nightlife, during your stay in Lisbon, this is the place for you! If you'd rather have quiet evenings, I suggest you look for something else.
I'm still fairly new to AirBnB, but this was by far my favourite place to stay at so far!
