I stayed in Mario and Elisabets apartment with my girlfriend for 5 days. They welcomed us very nicely even though we arrived later than the supposed check-in time. The communication with them went perfectly. The apartment is beautiful, ver new and modern. the bathroom was very clean and so was the kitchen, both fully equipped. We even used the sauna which was great. The location is great, not even a block away from nice cafés and restaurants. The nearest metro station is 10 minutes walking. We loved this place for our first time in Buenos Aires. There was even a rechargeable metro card in the appartment (this is the only way you can take the metro and bus in BA) so we didn't have to buy one ourselves. We would definitely recommend this apartment.
