Such a great place to stay for those people who are looking for a small flat in the heart of old Lisbon.
Flat is located in the vibrant bustling touristic place, near the Castle (but keep in mind it's almost at the top of a hill). There are a bunch of lively cafes situated literally over the housedoor, so it won't be a problem to have a breakfast once you step out. Or, if you prefer to cook by your own, flat is equipped with all necessary (and even more) stuff: microwave, coffeemachine, stove, oven, all needed pots and pans, etc. Another great thing is washmachine with dryer function - it really saved time for us.
So, to summarize: the flat itself is not really spacious, but cozy and very clean. I believe it would perfectly fit for 2-3 persons. Main bed is a type of double (140*200) plus a sofa bed. Bathroom has small but manageable shower. Kitchen, as it was said before, has all needed equipment.
João and Silvia made a great hosting, with instant communication and a lot of helpful tips. :)
I would definitely recommend this place to stay.
