This apartment is located in a perfect neighborhood. There is easy access to the bus and Metro and plenty is within walking distance. As indicated in the description, there is a very small elevator so be prepared to take more than one trip up if you have at least two people with two pieces luggage. Not a big deal at all.
There is a narrow staircase to the apartment so just be careful. Sebastian provides a very detailed house manual which should tell you everything you need to know. The manual indicates: "Please note that this apartment has not been renovated recently, there are some cracks and repairs needed here
and there, don’t expect it to be perfect. As a general rule, children less than 12 y.o. are not allowed."
Sebastian was very responsive to all my inquiries and very quick to respond. Enjoy your stay!
