The flat is large with private bathrooms and a shared kitchen which is well stocked.
The room is cozy and has a nice balcony (there are also 2 shared balconies in the flat).
The location of the flat is really nice as it is close to the center and to a major shopping street. The Metro station also is just a couple of minutes away.
Some points we didn't like that much about the appartment:
The smell of sewage in the bathroom was always present, sometimes just slightly and sometimes nearly unbearable. The bathroom couldn't be locked from outside so there was no way to make sure only we could use our bathroom (door is in the shared hallway).
Additionally, there were some thick black hair in our bathroom.
The communication with the hosts sometimes was insufficient as we sometimes didn't get an answer. For example, we asked them to restock the toilet paper as we only had half a roll but they didn't respond and didn't provide any, so we had to buy it ourselves.
The room had no AC (which is fine as it isn't stated in the listing) and we couldn't open the windows at night as the ACs of the neighbors were noisy. Due to this the room got really hot at night which sometimes made sleeping difficult.
We had a great time in Lisbon but due to the issues described above we probably wouldn't stay there again.
