Nick was great. We messaged a couple times before our arrival and arranged for him to meet us at the metro station by his place so he could show us how to get there (even after we were delayed at the airport for a hour because they lost one of our bags). He even pointed out some places for us to go as he showed us around the neighbourhood.
The room description was accurate and it was nice to have a bathroom to ourselves. Also, the Wifi was very good.
Nick even let us do a load of laundry at his place so we didn't have to find a laundromat.
The area itself is nice. We were able to find some nice bakeries and restaurants within walking distance, and the main tourist attractions were about a half hour walk away. There's also a small convenient store on the corner of the street.
