Great location in Chiado. lots of things to see and do within walking distance. Rossi station and Chiado metro stops are very close for easy access to all of Lisbon and beyond.
Apartment is average size and comfortable. Bathroom is small, and only a small fridge is in the unit (no freezer). Home has separate AC and heat in living area and in bedroom which is a plus. room darkening and noise reducing window covers were VERY useful. unit also has combo washer and dryer for small loads (just be prepared for 2-4 hour cycle).
Chiho has a binder with good detail on unit, local shops and restaurants, and access to transportation. also user manuals for everything ... except water heater. we had to reset it twice during our four day stay. only learned about that from previous reviews.
Big plus is that Laura (works with Chiho) met us at the unit during check in. she explained access to the building and gave us a quick walk through. She was our main contact during our stay.
