I visited Prague with my family. It was 6 of us and we fit perfect in this apartment. German & Elena were very helpful, communication with them was great. Their house is very clean, has nice kitchen, 2 bathrooms, one shower and 3 good sized bedrooms. The two larger bedrooms have windows facing the street. The decoration inside is elegant and modern. Also there is a living room with tv and sofa for relaxing and socializing. Metro and bus station are short walking distance and you can purchase tickets if you go down stairs at the metro. Very close to Prague if you feel like walking to the various sites self guided.
We really enjoyed staying at German & Elena's place and they are great hosts.
