We were two adults and a baby. The place itself was great for a baby. Every room had a separate door. Therefore, we were able to put our baby crib/cot in the living room, and then close the door to the living room to give the baby peace/quiet during sleeps. The bedroom itself is also big enough to fit our baby pack n play.
The place was well equipped, clean, and tidy. Bed was comfortable. There is a tub and a shower. Tub was useful for giving baby baths. Shower had good water pressure. There is a washing machine and a line to hang dry clothes. Kitchen had everything we need to cook all our meals. There is cable TV with english channels.
The location was perfect. You are no more than than 10~15 minutes to any major tourist sites. We were able to walk everywhere. Conveniently located near Rossio Metro Station (5 min walk) where you can get to Sintra, Cascais, or the Airport. There is a supermarket and public car park near by (5 min walk).
Monica and Bruno were great hosts. Monica checked us in in person and was able to accommodate and early check in. They were very responsive and answered all questions that we had about the apartment as well as tourists questions during our stay.
The only minor thing I will note is that their apartment is on the 2nd floor with narrow stairwell. This is common in many european cities. Therefore, it wasn't the most easy as we had lots of luggage/stroller/car seat/baby with us. Furthermore, the place was also somewhat up a hill, so if you are coming by public transit/by foot (which we did) be prepared to take longer routes to avoid stairs which Monica helped us with.
Overall, amazing airbnb where we would recommend this to anyone and we would be happy to stay here again.
