Great place in a vibrant ( and to our experience, safe) neighbourhood with a lot of history. Excellent amenities, tastefully furnished and modern place, sparkling clean, great connection to public transport and a lot of interesting places in walking distance. We instantly felt comfortable there. Lourenco provided an extensive list of things we could do. Keep in mind Lissabon is hilly with plaster roads, so bring shoes ;)
Things to check out nearby: Blabla Gluglu next door for tapas and a nice chat, free walking tour mouraria, story museum lissabon, zenith café (get there early), time out market (food stalls), fado bar sao miguel in alfama, Museum of Aljube Resistance and Freedom and many more.
