This is the best Airbnb experience Ive ever had. Marcelo's apartment is really fabulous. Not only is the apartment spacious and comfortable but it feels like a home - as though a friend has lent it to you - not an anonymous rental place. And the apartment facilities are amazing: there's a business centre, a proper gym plus a pool and jacuzzi on the rooftop! I spent half an hour on my last evening lying in the jacuzzi watching the sunset. And I loved using the gym - it is better equipped than one's I've used in 5 star hotels.
Marcelo made this a great experience too, he made sure I had everything I needed and responded immediately to any questions. But otherwise he was invisible. A perfect host.
Previously when I've been in DC for work I've stayed at bland hotels or conference centers. Never again!
