Tiago's place is well worth a stay for a short trip to Lisbon as was me and my friend, small and cosy but has everything you need. Would recommend two people max to stay here.
Pros: Tiago was very helpful, allowed us a self check in providing all details to access the building and the room itself, he also provided many recommendations of places to go, things to see, restaurants to try etc which was really valuable. Has everything you need, all amenities provided. Located very close to train stations (few minutes walk) and only a short 10 minute walk down to the sea or lots of bars, restaurants and shops.
Cons: No air con, had a fan but obviously not as effective as air con, we were quite hot at night. On a busy road, loud people and music till late at night so if you're a light sleeper then bring ear plugs. The smell of the lift to get up to the room is not the best, but obviously this is nothing to do with Tiago and so the 5 stars remain.
