We were 7 people and stayed 4 nights.
The place is cosy and charming, we like the fact that the room were a bit separated from the common area, it give you a bit of privacy when needed.
It is well located, the subway is not far, the mythic tram 28 is also close by.
And if you happen to arrive late there is take away pizzeria that close at 2 am.
The owner is really responsive to our request, we would probably come back there if we ever come back to Portugal.
