I stayed in the Remedios III with my family of 5 -- a couple, my mother, and two teenaged children.
We originally planned a three night stay, however, due to the east coast snow storm, our arrival in Lisbon was delayed by two days and we only had one night in Lisbon and in the lovely flat. The flat is located in the wonderful Alfama district, with many places to eat and interesting streets to wander. Convenient to public transportation, close to the river. The flat is as pictured and was clean. While the living/dining room is small, it is comfortable and has a great view. The real benefit is the number and size of the bedrooms. The four bedrooms are situated in such a way as to be private, and with three bathrooms, there is plenty of space for the group. The bedrooms are each large enough for a couple, with room for luggage.
We were very happy with the service from the time of our inquiry to the time we left. The management group Heart and Soul Lisbon responded promptly to our inquiry and answered all questions. When we asked for an early check in, they promised to accommodate us if possible, and then were able to do so. When I notified them that we would be two days late, they offered us an extension of two days (this was not possible for us). The manager met us upon arrival, and generously discounted our bill in recognition that the delay could not have been helped. As a Homeaway.com property owner and someone who has rented a number of properties, I can tell you that this is not typical! They also arranged a large taxi for us the next day so that we could go to the airport and pick up a rental car for the rest of our holiday, which took place outside the city.
We were very happy with our interaction with Heart and Soul Lisbon, and I will seek out one of their apartments if I have the opportunity to visit the city again.
