The apartment was extremely well located. A quick walk to multiple public transport modes and restaurants. The amenities were well thought out and the apartment was tastefully decorated.
Room was dark enough at night but you could hear a bit of noise from people drinking and eating till late. It's also quiet central so you have tipsy party-goers coming through the area. Unless you're a very light sleeper, it shouldn't bother you. Nothing ear plugs won't solve.
Check-in was a bother that day because the keypad was faulty and I had to go to the office nearby to pick it up. This was difficult because I drove down from Porto and there was no real place to park nearby. On top of that, the Google Maps link in their message was labeled correctly but linked wrongly which meant I ended up in a different place altogether. Luckily that was nearby and afterwards a quick call, it was sorted and I got the keys.
They asked that I drop the keys back off during checkout but I let them know I had a very early morning flight out and they allowed me to just leave the keys in the apartment. This was very much appreciate.
All in all, I'd certainly recommend it!
