We stayed at Robust (Miguel)'s apartment for exactly 2 months to spend the mandatory quarantine due to the Covid-19 pandemic. The apartment is located in Belém/Restelo, which is a nice neighborhood, and it is well equipped for short and long-term stays. The only inconvenience you might have while staying for long-term in the apartment is not being able to use the washing machine, the dishwasher and/or other devices at the same time since the electrical system will overload and shut down (a very common problem in Lisbon's old buildings). The initial apartment cleaning also wasn't the best since we found a male underwear behind the sofa and lots of dust below the beds when we arrived.
However, we recommend you to be careful in the communication with the host. When we self-checked in, he asked us to take care of the apartment and the plants, which we actually did, leaving the plants hydrated and everything else in the apartment in perfect use. Still, after we checked out, besides making a lot of unnecessary complaints about our lack of ability of cleaning - complaining mainly about the excessive use of the kitchen and bathrooms (without even considering we had to stay 2 months closed inside the apartment without being able to call anybody to help us clean it due to covid-19), he found a very, very small tear in one of the yellow dining table chairs and assumed that we did it (when we didn't), telling us we should pay for a new one - which didn't make any sense since the chair was perfectly useful and, as a host, he should know that the Airbnb Host Guarantee doesn't cover any damage from ordinary wear and tear. Anyway, we ended up solving the "lack of cleaning" problem by paying an extra cleaning fee, but we advise the new guests to make sure to take pictures of everything they see that is wrong or broken when checking in the apartment and also taking pictures of the conditions they leave it right before checking out. Another tip is to avoid keeping conversations with the host outside Airbnb's platform. Summing up, we hope that, through our review, the host can improve his client service ability in the future.
