The place is simply charming, cozy, clean and beautifully decorated. It has everything you need (from espresso machine to iron to spices). It felt roomy enough for two persons. It is quiet, being away from the main street. It is also very bright - we found the morning sunlight in the bathroom and in the kitchen charming.
It is located in a less touristy neighborhood (Graça), but close to downtown. A 2-4 minutes' walk away, you can find: the stop of the famous tram 28 (that can take you to Alfama and Castelo de S. Jorge or to Martim Moniz, very close to Rossio), super markets, pastry shops ("pastellaria"), small family restaurants and romantic miradouros (lookouts). The Intendente subway station is a 10 minutes' walk away. And Rossio Square is a 20 minutes' walk away, but it's a pretty steep descent.
This place is strongly recommended to those who appreciate a cozy, romantic place, away from the bustle of High Street, but within walking distance from it.
