Marius was an amazing host! He was so welcoming, informative and just genuinely interested in meeting new people. He didn't hesitate when I said I would come in late on Sunday night and also made sure I had everything I needed for the morning. For anyone staying here, I highly recommend an uber account for taxis. If you have one already in the US or anywhere else, it works automatically - no hassle! They are cheap and safe and the apartment is so centrally located it costs just a few dollars to get around quickly. The neighborhood is great during the day for walking around, but at night one should be a bit careful - just as in any downtown of a larger city one doesn't know well. The apartment is amazingly clean, the doorman downstairs is a wonderful guy - definitely worth having a chat with if you stay - and the wireless functioned perfectly. I also heard about power being out (brown-outs) in some of the fancy (and very expensive!) hotels my friends were staying at, but I never had an issue here. I was very lucky to have found this and recommend it highly.
