This was my worst AirBnb experience in the last 6 years. I rented over 40 places in different countries throughout the years, never had it been so unprofessional.
To start with, watch out when you book. In the house rules the guys who manage the apartment ask for 250 EUR security deposit, which they will try to charge you with a machine after you arrive. Don't do that. If you agree to pay, my advise would be to manage this through AirBnb Resolution Centre. At least then you know your money is safe. That's what I did. On top of "security deposit", if you check in after 8 pm, they would charge you a "late check in fee". I find this quite odd, to be honest. Never ever had I seen such a thing before. In general, I believe it's fair to transparently include all the charges in the listing price, when you book. I am not sure everyone checks the House Rules before booking, and I've never had a situation when host tried to charge me extra, or ask for a "security deposit". This was the beginning, and it only got worse.
The Wi/Fi in the apartment was quite bad. I wasn't really able to work using it during my stay, so I had to do a hotspot with my phone. So, if you plan to do some work from this place, this could be a problem. It's interesting that the property specifically has word "wi fi" in the listing name, and the wi fi is actually quite bad. Besides, there was renovation going on a couple of floors below, which was quite loud during the day (May 2021). To be fair, it was not the host's fault, but it didn't add any positivity to my experience.
Then a bad thing happened during my stay. The shower cabin door fell down after I took a shower and closed it. The door broke into tiny glass pieces and I had minor cuts over my body. The shower doors were fixed loosely - they are rolling, and they were supposed to be held on the rails by 2 sets of wheels, one set on top and one on the bottom. The bottom wheels were out of the rails, so the door was just swinging in and out. So, one time when I closed it, I guess, one of the top wheels also went off the rail and the whole thing collapsed.
The guys who manage this apartment didn't really try to investigate the accident or talk to me about it. They just sent a cleaning person the next day to wipe clean the floor and take out the glass (which I already collected in the trash bags). And basically the rest of my stay I was using a shower without a door, keeping my hands off of the second door completely for safety reasons.
After my stay, the property managing guys sent me a request to charge me 250 EUR and attached the invoice which was actually 40 EUR less... No apologies, no investigation on what happened. They also sent the pictures of the new door - looks like it's fixed in exactly the same way. So, if you decide to book this place, be very mindful that using this shower is actually dangerous. Lucky for me, and thanks to the fact that I insisted on using AirBnb to transfer the "security deposit", I got my 250 EUR back.
On the positive side, the location is good.
So, my recommendation would be to avoid this place and save your money and nerves. There are plenty of listings in Lisbon to choose from, which are safe and managed professionally.
