We stayed at Sandra's place for ten days, from where you can reach everything quite quickly. The apartment was clean and there was everything we needed. For a stay as long as ours we would probably take a bigger place with a prober kitchen next time, but for a couple of days it's just fine. It has air conditioning and everything to feel comfortable. Also, Sandra and her husband were very kind to pick us up from the airport when we arrived. The communication went perfectly well and was super quick and kind. We can totally recommend the place for a couple days of exploring Lisbon.
