We only stayed at Vladimir's place one night on a long layover in Paris and highly recommend it. His location is walkable to Sacré-Cœur and a lot of wonderful artists, shops, and restaurants. Some reviews complain that his place is small but in my opinion if you're doing more than sleeping there you aren't doing Paris justice. I arrived earlier than my check in time although I was able to check my bag near by at the Hotel Sofia through Nanny Bag. He recommended taking the Metro to the airport the next morning although with an early flight that wasn't an option but I was able to reserve a taxi for the next day. I will say his place does have a lot of windy stairs so be warned if you have trouble carrying big bags up several flights. Once again, I highly recommend staying here, especially if you want to check out Montmartre. Thanks again.
