Perfect location, very nice space.
We loved My Suites. It's in an ideal location - just a block from some very nice shopping and restaurants to the North, and an easy walk to Chiado, the TimeOut Market, Castelo de São Jorge and more.
Bairro Alto - the neighbourhood around My Suites - is a clubbing area (which may be to your liking or not). It can get quite busy at night. BUT: the street that My Suites is on is dead quiet. We could not hear any noise at night, even with our courtyard window open. Just the occasional car on the road behind.
