Stayed at this flat for 3 nights in May 2021.
To summarise, it's a great flat, modern, well decorated, quiet and in a great location to explore the historic part of Lisbon (Alfama).
Positives:
* Great location close to two lines of "old" Trams (28 and 12) and minutes from the Castle. Also, close to several great view points. There is also a bus nearby (I think the only bus line in Alfama, going to the castle entrance), which can be cheaper and less busy that the trams
* Nice building, recently done
* Flat is in very good condition, spotless and well decorated
* Plenty of light, three windows with some nice views
* Plenty of storage in the bedroom
* Good large bed
* No noise whatsoever from the street, due to the very effective double glazing windows
* Powerful air conditioning
* Large shower, powerful flow, all marble bathroom
* Good kitchen, with microwave oven, Nespresso machine, washer/drier, hob
* Very good communication from the host
* The lady from the concierge service was right on time to provide the keys, give a tour of the property. Very friendly too
Some (small) negatives (some already provided in other reviews):
* Towels provided are a bit thin and basic
* Steep and narrow inside stairs to get to the flat, on the second floor. Could be an issue with some large suitcases, but only for a short distance
* Nothing provided to clean the dishes (no sponge, no brush, no rags)
* No soap provided for the shower or other toiletries
* Nowhere to keep the shower head attached (have to hold by hand)
