We stayed at Gonçalo’s for New Year’s Eve and it was excellent, you can enjoy the fireworks from the balcony.
The street is unbelievably busy at night but the windows are noise proof and the bedroom is interior so it is not a problem if you want to go to sleep early. Why would you, though, when you have all these excellent bars around with great music.
Gonçalo was super accommodating and helped us with everything we needed, including a late check in, then a late check out.
