The apartment was indeed very nice and in a a great location although a little noisy from the road. However I had booked the apartment because it was profiled as Alex's home where he lives. On arrival it turned out he no longer lives there and there were two other guests staying at the property. I certainly would not have booked to stay here if I had known this 1/ there is a safety factor for single women travellers about knowing where and who we are staying with 2/ my preference is to stay in places which support locals and not a hostel type environment 3/ being woken up at 2 pm in the morning because of a hostel type culture with guest coming and going late at night. 4/ unfortunately the electricity was also not working properly so I was unable to charge my phone or computer making my one day in Lisbon hard work and having to stand holding the fuse switch up to have one cup of tea in the morning.
Airbnb started out as a way for people who had spare rooms to make a little extra and create extended communities- It's really sad that it is just another neo-liberal entity with apartments bought or rented on the basis of making a living through this forum- raising the prices of permanent accommodation for locals. Its a real shame!
