Me and my girlfriend booked the tiniest room for 3 nights in the beginning of September. From previous reviews we had expectations that it'd be a bit hot and stuffy but the location was excellent so no complaints. The apartment is clean and has everything one would need even though some improvements could definitely be made...
1. There's a dryers machine that's constantly on and adding at least 5 degrees on top to the already unbearable heat in the apartment which is on the last floor (5th) of the centrally located building. When on, the bathrooms becomes a sauna and you can't survive there for more than 5 minutes.
2. 3 people were unable to start the coffee machine so bear this in mind.
3. This Las remark has nothing to do with the flat but one of the roommates ate all of our sweets without permission which wasn't cool but what can you do... The risks of sharing an apartment with random people always poses hidden risks.
All in all, good value for money but I would never return to the listed residence. Falling asleep was super difficult, even with the provided fan, blowing straight into our faces. You need your rest in Lisbon as 25k+ steps every day is the beat minimum you gonna get away with if you're a proper explorer.
