Great location if you are confident in understanding the subway/tram systems. We walked the first day to the Altstadt area, the second day we took the subway :) There is a nice beer garden fairly close, as well as a coffee shop that serves breakfast. Nice Italian restaurant right downstairs. The balcony is nice in good weather to sit and have a coffee/snack.
When we arrived in the afternoon when the weather was quite warm, as was the room--no central a/c (as stated in the description). We arranged for a portable a/c in advance, I'm glad I did otherwise the temp would be uncomfortable during the day--at night it is very nice even in the summer, u can leave the door to the balcony open and it is generally very quiet at night, even on the weekend. The a/c being portable means that you have to run the exhaust out the door to the balcony, which we had to use some caution with when it rained one night. Other than that the room has everything u could want: kitchen sink and stove, small refrigerator, shower and soap, etc. Wifi was decent but would dip out temporarily, occasionally. The bed is firm, fine by as is mine at home--if u have to have a super-soft mattress though u might not be comfortable.
Overall a great stay, couldn't beat the location for us. Thanks Dete!
