Erik's studio is located in one of the best neighborhoods in Paris: the 7th Arr. We felt safe walking home at night. The 1 flight of staircase to reach the studio is considered good since many of the older apartments in Paris (with no lift) listed in our accommodation search are located in the 4th or 5th floor. Our check-in & check-out was self-service, Erik emailed after the check-in day to ask if we need anything. Wi-fi connection dropped every 3 minutes or so (meaning you need to re-enter login details), thus we found other means to get connected.
