Let's start with this. If this apartment if available for the dates you're seeking and you're reading this review, stop now and book it before some else does.
That said...there isn't a whole lot to say that hasn't been said in the reviews that got me to stay here. Teresa is a phenomenal host who met me at the door to show me her and her husband's absolutely lovely apartment. It is a fantastic jumping off point for discovering the beautiful city of Lisbon.
I was spoiled as a solo traveler because their place can easily accommodate multiple travelers. It's impeccably clean, comfortable, and tastefully designed.
Even better, as previously mentioned, Teresa met me and provided me with local suggestions for eating and drinking that proved invaluable as I am someone who would much rather a local resident's opinions that an arbitrary star rating on Google or wherever.
Just book it. You won't be disappointed.
