The flat is very well located. The city center / Cathedral can be reached in 10-15 minutes by feet. The metro station in about 5 minutes. 2 minutes away one will find the main shopping street with small coffees and many nice shops and bars. The flat itself is a small but very nice 2 room appartment, equipped with everything one need, only a dish washer is missing.
I would recommend the flat for a couple or a small family with max. 1 child as the living room is small and the current studio couch is ok for a small kid but not recommended for an adult (for 1 or 2 nights it is ok but not for a longer stay). The bed room does not have enough space for an additional kids travel bed.
The communication with Matilde was very good (fluent English) and she is very kind.
The appartment is indeed recommendable!
