I really enjoyed my brief weekend stay at the Lanchid 19 Hotel.
The staff were friendly and courteous and spoke impeccable English. Nothing was too much trouble and they were very happy to organise taxis, store luggage etc... I had a very early flight into Budapest and so arrived at the hotel at 10am, hoping to be able to store my suitcase, but they had already prepared my room and so I was able to check in straight away.
Breakfast was included and was both plentiful and delicious, with a nice quiet patio at the rear of the hotel.
The room was spacious and well-appointed. It's also very quiet! If you can, book a room facing the Danube as the hotel looks out onto the lion bridge and the houses of parliament and the views are great. It's also very handy for exploring the castle district and a short walk across the lion bridge brings you to the main commercial area of Budapest.
In short, highly recommended!
