we have stayed at Marc´s studios two nights and all was great. before we arrive, Marc gave us the instructions to get to the studio and then he was there waiting for us and he explained all about the stay and gave us maps of the city. The studio is small but is comfortable and new and it is located in the heart of Paris, only two minutes from Madeleine and Opera and about half and hour walking from Notre Dame. The only thing which isn´t perfect is the noise, so, during the night the pipes of the building are noisy. Although our visit was wonderful!
