We had a great time in Buenos Aires and staying at Claudia's place was one of the main reasons. We spent 10 nights staying in Palermo and our experience from the house was A-M-A-Z-I-N-G.
Super clean, very cute, balcony rules and the big tree in front of it will make you feel you're in a camping (almost!). Palermo is a really nice place to be, full of life, bars, restaurants etc and not far from the centre.
The best of all though was Roxana's help (Claudia's friends and our guard while we where there). Extremely helpful and warm from Day 1, she made us feel at home and gave us also great tips.
Claudia was super helpful too with all our communication from the beginning and doing her best to accommodate are fluid schedule.
The place is a great value for money but apart from that you will feel very nice living there. It has beautiful vibes. DON'T MISS IT.
