Staying at Maggie's was a delight. She was very thoughtful, gave us a ton of information about Lisbon and the surrounding places of interest, plus some tips and tricks on where the food was good and affordable or what places to see first and when.
The place was small but very well thought out, we had everything we needed, very clean and cosy.
The location is great, small walking distance from many land marks and many great restaurants.
All in all we recommend staying at Maggie's (any of the 4 apartments).
