It's a lovely place to stay, particularly if you're out and about, at a very reasonable price and in a great location. I pretty-much walked everywhere, but the trams and buses were very close by.
It's very beautifully done up, but there are some drawbacks - (a) I believe many places in Lisbon have an issue with musty dampness in winter, and this was the case here, (b) during my stay I could hear *everything* that the upstairs neighbours were up to!!! and (c) the bed wasn't the most comfortable for me.
Overall, however, I really enjoyed my stay there. Lisbon is such a great city! Thanks.
