Area is not so nice and safe, but if you are a little bit adventurous type, it will suit your needs.Only one problem is parking - there is place for parking in street next to hotel, but hotel stuff states, that it is on your own risk - no camera, no guard. As other visitors advised, breakfast is nothing special. If you can start your day with one type of yoghurt, three types of salami and bread, you are OK. Eggs and sausages looked ugly each day. But when you will stay only for a few nights, you won't starve to death. We had breakfast included in price, which was so low, that we did not expected nothing special.
First of all, price of this hotel is really low in comparison with other ones in three stars category near Budapest center. Location is very good - 20 minutes of walk to Varosliget park and 10 minutes walk to Stadion metro station. There was quiet at night during our stay. WiFi was best of all hotels we stayed in - reliable connection, good speed (20 MB/s download. 8MB/s upload measured on iPad. You will find free place without problem and if you park wisely, you can see your car from window of your room. Room was clean and cleaning stuff checked room each day. Stuff on reception was very friendly and helpful.
