The TM Apartment staff was wonderful. You get the full service of a hotel staff with housekeeping and reception. The place was very clean and spacious. The door to the unit is like a bank vault door, so we as a family felt super safe.
Regarding the amenities, the location is central - just steps away from Rossio station (main station) and the main shopping area with many wonderful restaurants nearby. The bathroom is beautiful and the bed is comfortable with closet space to put your clothing. The kitchenette has enough to make a breakfast with bowls, pans, cups, and cutlery. Additionally, there is a beautiful garden outside that guests have access to.
The only downside is you have to put €100 for incidental damages during the stay so as a tourist, so make sure you bring extra euros to accomodate this. They do have this posted on the airbnb listing.
The best part of the stay was the staff. Everyone is very helpful and friendly. Orlando in particular was very accomodating by letting us put our stuff with him before check in (we arrived early). He walked us through the entire unit and gave us the tour, very friendly and knowledgeable. If I was to travel to Lisbon again, I would definitely stay here for its cleanliness, staff, and location. Highly recommend!
