I had booked the apartment for a whole semester studying at NOVA with a friend and we couldn't have been happier with everything Margarida and Michael have done for us, as this stay at their apartment has most definitely enhanced our Lisbon experience to the fullest degree!
First contact was very lovely and kind. And though at the time both hosts were in NYC, they had a friend of theirs (very nice, competent and totally funny) personally come over to hand over keys and look into apartment together (which, by the way the pictures don't do justice because the apartment itself is by far one of the nicest ones I have lived in!). Nonetheless, I was always able to contact both Margarida and Michael via airbnb message, and Margarida even came by the apartment right before we left to leave some candy - wish the two would have spent more time in Lisbon so that we could invite them for a thank you dinner (maybe next time ;)) All in all, the two did everything to comfort us and we could perceive that they want their guests to have a great and comfortable time - keep up the great hosting!
Again, the apartment itself is simply stunning. 2 huge bedrooms (with equally big beds) and a smaller bedroom that still fits a grown person with no problem at all. High ceilings, 2 very nice bathrooms, a beyond fully equipped kitchen, TV & hifi entertainment systems and the terrace is really cool - for eating, chilling out, hanging out in the lovely hammock - especially during the warm Lisbon days and nights.
The neighborhood is in a good location to reach everything by foot or subway (Arroios around 2 min walk away), for tourists with a couple of spare days in Lisbon definitely a great place and a lot less stressful than living in busy Bairro nightlife districts. Cervejaria Ramiro - the renowned seafood restaurant - is around 10 min away, would definitely recommend going there and booking a table (up top on 2nd floor, so one does not have to stand in line for ages!).
Could leave a lot more impressions based on the 4 months we lived in Lisbon and stayed in Margarida's and Michaels apartment, but I would simply advice that if you are planning on going to Lisbon, keep this 5+ apartment in mind! Such a lovely place and very nice hosts, it was a bittersweet moment for us two when we had to leave the place.

Thank you Margarida and Michael again for this great time!

Cheers,

Nick & Lars
